Migrate from Activiti 5.17

Camunda 7 Topics Discussion & Questions

Hi,

I have some running processes with data in Activiti 5.17.

I would like to migrate but Activiti database schema seem to have changed since fork (5.11).

Is there a documented process to migrate without data loss ?

Thanks.

Hi @bensopra,

There is no such document in the official Camunda documentation. The effort of maintaining that for all combinations of Activiti and Camunda versions would be too big. I also think that migrating running process instances may be non-trivial (especially entries in ACT_RU_EXECUTION and their references).

If you have specific questions on the Camunda database schema, feel free to ask them here.

Note that you can also use dynamic process instantiation to start process instance at any activities. Perhaps you can simply restart your running process instances with Camunda.

Cheers,
Thorben
