Could not update Flowable database schema: unknown version from database: '6.7.0.0'

Dear Flowable Team,

I hope this message finds you well.

We are currently facing an issue in our application related to the Flowable database schema. One of my teammates has been working on upgrading our Spring Boot application and updating the Flowable database. However, when we attempt to run the application with the older version of Flowable (version 6.3.0), we encounter the following issue:

The application is expecting a newer schema version (6.7.0.0) but the database is currently set to 6.3.0.1.

As we are using Java 8 and intend to continue using Flowable version 6.3.0, we would like to downgrade the schema to the appropriate version that matches Flowable 6.3.0.

Could you please provide the migration scripts or guidance on how we can downgrade the database schema to version 6.3.0?

Your assistance in this matter would be greatly appreciated.

Hey @Hargundas11,

We do not support downgrade from a newer Flowable version (e.g. 6.7) to an older one (e.g. 6.3). If you did something like this, then you’ll have to look at the DDL between 6.7 and 6.3 and create your own SQL scripts for the cleanup.

Cheers,
Filip
