Customers already using event based processes should see no difference for their already published event based processes. This might require a migration if there is a data structure change, but this will be invisible to the end user. We should have tests that make sure that previously published event based processes are still retrievable and still able to correlate events as expected.

ATs:

• Previously EBPs are unaffacted
• We have ITs to ensure this
• If a migration is applied, we have ITs for existing EBP fetching/correlation behaviour
