Supported migration paths

You can migrate from IBM App Connect Enterprise 11.0 or IBM Integration Bus 10.0 to either the Advanced Edition or Standard Edition of IBM App Connect Enterprise 12.0; do not migrate integration nodes or servers to the Developer Edition.

You can use in-place migration to migrate integration nodes to IBM App Connect Enterprise 12.0, as described in Performing an in-place migration of an integration node.

You can use either parallel or extract migration to migrate integration nodes and managed integration servers to IBM App Connect Enterprise 12.0, as described in Performing parallel migration for an integration node and Performing extract migration of an integration node or integration server.

Independent integration servers that were created in IBM App Connect Enterprise 11.0 can be started in IBM App Connect Enterprise 12.0 without the need to migrate them or their resources. However, integration server work directories are typically created as transient rather than long-term artifacts, and many users prefer to rebuild them when they move from one version to another.

You can use the IBM Integration Explorer view of the IBM App Connect Enterprise Toolkit to add connections for integration servers and integration nodes. IBM App Connect Enterprise Toolkit Version 12.0 supports Version 12.0 integration servers and integration nodes only. Connections to integration servers and integration nodes that are running on previous releases are not supported.
