What value are you using for databaseSchemaUpdate in the process engine configuration? Which version of 5 are you upgrading from?

Best regards,

Hi,

Version 5.22.0 was not included as a valid version in a version 6 Engine release yet. Therefore the version 6 Engine will not know the version and will create all tables from scratch again. On Master we did included 5.22.0 as a valid version and there it will work without any issues I expect. We’re close to release a new version 6 Engine with version 5.22.0 included.

Best regards,

Tijs
