Hi Support, I would like to upgrade from Core v.4.9 to 9.0. (self-hosted postgresql) I get an error message about a foreign key constraint that does not exist. Is there a migration script I have to run, do I have to upgrade incrementally?

hey @mr.lurs you should see the CHANGELOG.md file here for migration steps: https://github.com/supertokens/supertokens-core/blob/master/CHANGELOG.md

ah I see, thanks a lot 🙂
