Spring Boot 3.2 upgraded its dependency on H2 to v2.2.224 Since version 2.2.220 H2 has a new format of db files which is incompatible with v2.1.214

This upgrade of db must be done manually.

Maybe I'm wrong but because of such incompatibility SB 3.x should stay with 2.1.214 and postpone upgrading to v2.2.220+ to SB 4.x

I don't think it's sensible for us to remain on H2 2.1.x indefinitely, I think it's better that we upgrade and persuade users to migrate their database files. If you don't want to do that, you can set the h2.version property in your build to downgrade.
