Preparing for migration

Plan the order and extent of the migration of components and resources to IBM® App Connect Enterprise 12.0.

1. Check that your current installation of IBM App Connect Enterprise Version 11.0 or IBM Integration Bus 10.0 is at a supported level for migration (see Supported migration paths).

   For the latest details of all supported levels of hardware and software, see the IBM App Connect Enterprise system requirements website.

2. Some function that was available in IBM Integration Bus is not currently available in IBM App Connect Enterprise 12.0; elements of this function are to be made available in fix pack updates. For details of which commands, policy types, and other resources are unavailable in IBM App Connect Enterprise at this fix pack release, see the Frequently asked questions about IBM App Connect Enterprise website.
3. Determine your migration priorities by following the steps in Migration planning.
4. Review the options that are available to install IBM App Connect Enterprise 12.0 components on the same computer as components from IBM App Connect Enterprise Version 11.0 or IBM Integration Bus 10.0 (see Coexistence of IBM App Connect Enterprise 12.0 with previous versions).
5. Learn about new and changed function in Version 12.0 by reading What's new in Version 12.0?.
   These changes might affect how you want to use your migrated components in the future.
6. Review the IBM MQ configuration options that you can include in your migration plan in IBM MQ and migration to IBM App Connect Enterprise 12.0.
   These changes might affect your choice of integration node migration option.
7. Review the options for migrating your integration nodes and integration servers, and decide whether to use extract migration or parallel migration (see IBM App Connect Enterprise migration options).
8. Review the technical changes in behavior in Version 12.0 in Behavioral changes in Version 12.0.
   These changes might affect your post-migration development tasks.
9. Check the requirements for other products on which Version 12.0 components might depend.
   If you configured your message flows to use external resources, such as databases or event monitoring applications, you might have to modify your configuration. You can find details of supported versions of complementary products on the IBM App Connect Enterprise system requirements web page.
