BPM Upgrades - Which comes first - Process Center or Process Server ?

This question arises from time to time, so I thought I'd capture the official IBM position from the IBM Support Page: -

The Process Center and Process Server versions do not need to match, and Process Server V8.5.7.201606 can connect to an earlier version of Process Center V8.5.x. You can upgrade Process Server first and test your applications to make sure that they still work normally after the upgrade. Upgrade Process Center last. For more details, see Performing a rolling upgrade

You can also use offline deployment between Process Server V8.5.7.201606 and an earlier version of Process Center V8.5.x.

Not including Process Server, the tools and related user interfaces that interact with Process Center must be at the same version and release level as Process Center. The repository does not support the previous release; only the current release. Even though you might be able to connect an installation of IBM Integration Designer at the current release level to a Process Center at the previous release level, you should not publish any process applications that have gone through artifact migration.
