Connectivity Agent Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
Agent Java Version	Development Operations team	No	Make sure that your connectivity agents use JDK 17 and PKCS12 KeyStore. Expand More details to see the connectivity agents that need review, or view the Connectivity Agent Status section to see the status of all the connectivity agents in your instance. For any connectivity agent that isn't already using JDK 17, install JDK 17 on the server that hosts the agent. For any agent that is still using the JKS KeyStore, convert the KeyStore to PKCS12 KeyStore. You can do the conversion in one of two ways: Automatically, during upgrade: Your JKS KeyStore will automatically be converted to the PKCS12 KeyStore during upgrade. Manually, before upgrade: You can convert the JKS KeyStore to the PKCS12 KeyStore manually, before upgrade, by following the steps below. Note Converting the JKS KeyStore to the PKCS12 KeyStore doesn't impact your Oracle Integration Generation 2 connectivity agent, and only takes effect after you have upgraded to Oracle Integration 3. If you want to manually convert your JKS KeyStore to the PKCS12 KeyStore, complete the following steps before upgrade. These tasks require you to briefly stop and then restart the connectivity agent, so choose a time when the connectivity agent isn't being used. On the server that hosts the connectivity agent, create a backup of the `keystore.jks` file, which is located in the following folder: `Agent_Install_Location/agenthome/agent/cert` Move the backup file to a different folder. Convert the JKS KeyStore to the PKCS12 KeyStore by running the following command from the command line: `keytool -importkeystore -srckeystore keystore.jks -destkeystore keystore.p12 -srcstoretype JKS -deststoretype PKCS12 -deststorepass changeit -srcstorepass changeit` Stop the connectivity agent. Delete the `keystore.jks` file in the following location: `Agent_Install_Location/agenthome/agent/cert` Start the connectivity agent.
Agent Connectivity for Oracle Integration 3 - Connectivity agent must be running	Development Operations team	No	Make sure the connectivity agent is up and running before the upgrade begins. Expand More details to see the connectivity agents that need review, or view the Agent Status column in the Connectivity Agent Status section to see the status of all the connectivity agents in your instance, indicating whether each agent is offline (unavailable). Agents that are offline during upgrade or don't meet upgrade requirements won't be upgraded, in which case you'll need to perform post-upgrade steps to regain connectivity.
Agent Connectivity for Oracle Integration 3 - Update your allowlist settings	Development Operations team	No	Before upgrade, you must update your allowlist settings for your connectivity agents. Expand More details to see the connectivity agents that need review, or view the Allowlist status column in the Connectivity Agent Status section to see the status of all the connectivity agents in your instance, indicating whether the allowlist has been updated appropriately. As your upgrade window approaches, perform the following pre-upgrade tasks: Add the IP address for Oracle Identity Cloud Service (IDCS) to the allowlist. Add the design-time and runtime IP addresses for Oracle Integration to the allowlist. Set the proxy server's Cache property for the Oracle Integration URLs to refresh as frequently as possible. Agents that are offline during upgrade or don't meet upgrade requirements won't be upgraded, in which case you'll need to perform post-upgrade steps to regain connectivity.
Unsupported AgentGroup Identifier	Development Operations team	No	If any of your agent groups have a space in their identifiers, they won't be migrated to Oracle Integration 3. If you still need the agent groups, you'll need to recreate them after upgrade.

Instance Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
Custom Endpoint URL	Administrator	Yes	If you use a custom endpoint, you'll see no difference in runtime access to your integrations after upgrade. For all other access points—design-time, Visual Builder, Process Automation—you still access the custom endpoint, but the custom endpoint then redirects to the appropriate URL. If you use a custom endpoint for your instance and your instance is failing this precheck, expand More details to see what is causing the failure: Using SSL: Set up a load balancer as a front end for your Oracle Integration Generation 2 instance, and remove the SSL certificate from your Oracle Integration Generation 2 instance. See Configure a Custom Endpoint for an Instance. VBCS is enabled: Oracle Integration 3 currently doesn't support Visual Builder with a custom endpoint. Wait until Oracle starts upgrades for this feature, or, if you want to move forward with upgrade now, delete the custom endpoint from your Oracle Integration Generation 2 instance. Alternate Custom Endpoint used: Oracle Integration 3 currently doesn't support alternate custom endpoints. Wait until Oracle starts upgrades for this feature, or, if you want to move forward with upgrade now, delete the alternate custom endpoint from your Oracle Integration Generation 2 instance.
Instance ID Action	Administrator	No	The system-generated instance ID that is displayed on the Instances page and in the activity stream for an integration instance has changed from a numeric value to an alphanumeric value in Oracle Integration 3. The value's data type is unchanged; it remains a string data type. The change to an alphanumeric value may affect any systems that you use that rely on the instance ID being a numeric value. For example, if you parse the instance ID from a REST API and store the instance ID in a database as a number field, you'll need to update the database field. If you have integrations that use instance IDs, the precheck shows a warning. Expand More details to see the integrations that need review. Then update your systems and processes as required. See Adapting to Instance ID Change when upgrading to Oracle Integration 3.
Daily Email Limit	Administrator	No	Oracle Integration 3 can send a limit of 10,000 emails in a rolling 24-hour window, as described in Service Limits. If your deployment needs to send more than that, you can instead use your customer tenancy. See Configure Notification Emails.
Custom scopes in IDCS	Administrator	Yes	Oracle Integration 3 adds a default scope (`/ic/api/ , urn:opc:resource:consumer::all`) to Oracle Identity Cloud Service (IDCS) when the instance is created. It doesn't support any other custom scopes added to IDCS. If you have created custom scopes in IDCS, you must remove them.
Other Failures	Varies	Yes	If there are any other issues that will block upgrade that don't have specific prechecks, they'll be included under other failures. Expand More details to see the issues that need action.

B2B for Oracle Integration Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
B2B Retention Period	Administrator	No	Although you don't need to do anything to correct this precheck status, be aware that Oracle Integration 3 Standard and Enterprise editions support 32 days of data retention by default. During upgrade only the most recent 32 days of retained data will be migrated. Expand More details to see how many days of retained data you currently have.

Integrations Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
Delayed (Asynchronous) Response	Development team	Yes	The delayed (asynchronous) response pattern was previously supported in the following adapters: Oracle CX Sales and B2B Service Adapter Oracle ERP Cloud Adapter Oracle HCM Cloud Adapter Oracle Field Service Cloud Adapter Salesforce Adapter ServiceNow Adapter If you have integrations using delayed (asynchronous) response with one of these adapters, rework them by creating two invoke connections to achieve similar functionality: Create a simple invoke for success callbacks. Create an additional invoke for failure callbacks under the fault handler to catch the correct fault. Expand More details to see which integrations need review.
Identity Certificates	Development team	No	Identity certificates establish client identity during two-way SSL communication. Connections that are based on the AS2 Adapter and the REST Adapter can use identity certificates. Expand More details to see the names of the identity certificates and the connections that use them. If you have identity certificates, after the upgrade, you'll need to upload new identity certificates as described in Ensure Connectivity:
Basic Routing Duplicate App Name	Development team	Yes	If your instance contains basic routing integrations that have the same source and target endpoint names, perform the following steps: Edit your basic routing integration, deleting the target endpoint, and adding it again with a different name. Save your integration. Expand More details to see the integrations that need review.
Number of Active Integrations	Development team	Yes	An instance can have a maximum of 700 active integrations, as specified in the Service Limits. If you have more than 700 active integrations, reduce the number by deactivating or remodeling integrations.
Multiple Read File	Development team	Yes	The Read Multiple File operation was deprecated in Oracle Integration Generation 2. If you have integrations that include an operation to read multiple files, rework the integrations so that they don't use this pattern. For example, use a listFile operation to list the files, and use a for-each action to read each file individually. Expand More details to see the integrations that need review.
Publish/Subscribe Integrations	Development team	Yes	If your instance includes integrations that publish messages or subscribe to messages from Oracle Integration, be aware that publish/subscribe (or pub/sub) integrations need to be converted to event-driven orchestrations. The integrations will be handled differently depending on their configuration: Pub/sub integrations that use a REST adapter trigger with JSON or XML payloads are automatically converted during upgrade. Pub/sub integrations that use a template parameter or a query parameter are automatically converted during upgrade. However, the parameters are removed during conversion. After upgrade, you must reimplement these parameters in the event's custom header. See Define Header-Based Subscription Filtering in Using Integrations in Oracle Integration 3. Pub/sub integrations that use multipart/form-data, multipart/mixed, or binary payloads can't be automatically converted at this time. If you want to proceed with upgrade, remove these integrations, and then, after upgrade recreate them, defining custom headers for the events. If the integration uses an attachment, you can push the attachment into the FTP server or Object Storage in your tenancy and pass the reference to the subscriber flow. See Define Header-Based Subscription Filtering in Using Integrations in Oracle Integration 3. Pub/sub integrations that use an adapter other than a REST adapter can't be automatically converted at this time. If you want to proceed with upgrade, remove these integrations, and then, after upgrade, recreate them. See Create Integrations to Publish and Subscribe to Events in Using Integrations in Oracle Integration 3. If you see the error Only Subscribers are present, no Publishers, you have orphan subscribers that must be deleted before upgrade. Expand More details to see the integrations that can't be automatically converted. Note: You might want to take this opportunity to delete any draft Publish flows.
DT API Basic Auth to OAuth action	Development team	No	If your instance includes integrations that access DT (design-time) built-in APIs using a REST connection with basic authentication, you must change them to use OAuth. In Oracle Integration Generation 2, you could use Basic Authentication to use the Oracle Integration REST API and File Server REST API. In Oracle Integration 3, you must use OAuth. You need to update any clients, scripts, integrations, and commands that use the Oracle Integration REST API or the File Server REST API to connect using OAuth. For more information on authentication method support, see When is Basic Auth Supported in Oracle Integration 3. For details on using OAuth with the Oracle Integration REST API, see Security, Authentication, and Authorization, or with the File Server REST API, see Security, Authentication, and Authorization.
XSLT function definition	Development team	Yes	Custom XSLT function definitions that were added manually in the mapper aren't supported at this time. You can wait for Oracle to add support for this functionality, or, if you want to proceed with upgrade now, rework or remove the integration. Expand More details to see the integrations that include custom XSLT function definitions.

Adapters Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
Custom Adapters	Development team	Yes	If your instance includes integrations that use a custom adapter, the instance can't be upgraded yet. Wait until Oracle starts upgrades for this feature. Expand More details to see the custom adapters you're using.
Oracle Utilities Adapter	Development team	No	Swagger 2.0 is no longer supported in the Oracle Utilities Adapter. If there is any existing integration using the Swagger 2.0 REST catalog, runtime won't be impacted. However, if you try to edit the design-time connection, retest the connection, refresh the metadata, refresh the artifacts, or reactivate, the integration fails. You must update the catalog to use the OpenAPI 3.x definition. Expand More details to see the integrations that need review. See Using Swagger 2.0 REST catalog with Oracle Utilities Adapter version 24.04.0 or higher.
Unsupported Adapters	Development team	Yes	If your instance includes an integration that uses one of the following adapters, which aren't supported in Oracle Integration 3, replace the adapters with the REST adapter: Automation Anywhere Adapter Evernote Adapter Oracle Messaging Cloud Service Adapter Oracle Monetization Cloud Adapter Oracle Taleo Business Edition (TBE) Adapter UiPath Robotic Process Automation Adapter Expand More details to see which unsupported adapters you're using. Note that robotic process automation (RPA) capabilities are available in Oracle Integration 3. See Learn About Robots and Build a Robot in Using Robots in Oracle Integration 3.
Unsupported REST Types	Development team	No	The following connection types are deprecated and not supported in a REST Adapter connection. Replace these connection types with different connection types. See Configure Connection Properties for Invoke Connections in Using the REST Adapter with Oracle Integration 3. Metadata Catalog URL Swagger Definition URL RAML Definition URL Expand More details to see which unsupported REST types you're using. Developers with a REST API that is described using RAML or the Oracle metadata catalog must take the following action: Consult your REST service provider and ask for a Swagger definition (if available). Oracle Fusion Applications should have a Swagger option available. This is a guideline for all Oracle Fusion Applications. If an alternative spec is not available, use the basic template in the REST Adapter by selecting REST API Base URL as the connection URL and defining the target API request using the Adapter Endpoint Configuration Wizard. Another option is to convert RAML into an OpenAPI specification to use with the REST Adapter connection. To provide more robust and complete support for the Swagger/OpenAPI specifications, the REST Adapter includes a unified option to specify all OpenAPI specifications in a single field. This option also replaces the option to provide a Swagger definition URL, which is no longer available.

Visual Builder Prechecks

Eligibility condition	Typical owner	Blocks upgrade	Tasks to Complete
VBCS	Administrator	Yes	If you use Visual Builder with your own Oracle database instance (BYODB), Autonomous Transaction Processing (ATP) must be up and running during upgrade. Make sure to complete the additional Visual Builder Pre-Upgrade Tasks.
VBCS-PWA	Administrator	Yes	Oracle Integration 3 doesn't yet support Progressive Web Apps (PWAs) created with Visual Builder. To see which apps are blocking upgrade, expand More details. If you want to proceed with upgrade: Delete those apps. Rerun the precheck. After upgrade, recreate the apps. Make sure that any devices running the apps uninstall the old apps and install the new ones.

Process Automation Prechecks
