There are no persistence changes between 2.0.202 and 2.0.204, so jar file swap is enough, if database had been upgraded to 2.0.202 already, otherwise please read the message below:

Between version 1.4.200 and version 2.0.202 there have been considerable changes, such that a simple update is not possible. The official way to upgrade is to do a BACKUP of your existing database USING YOUR CURRENT VERSION OF H2.

Hi @treo, the dependabot suggests us to update the h2 to the latest version due to security vulnerability, is that ok to do so?

[treo]

Between version 1.4.200 and version 2.0.202 there have been considerable changes, such that a simple update is not possible. The official way to upgrade is to do a BACKUP of your existing database USING YOUR CURRENT VERSION OF H2. Then create a fresh database USING THE NEW VERSION OF H2, then perform a SCRIPT to load your data.

This means we can't just update it without an additional migration step.

I think this may be a good opportunity to factor out the migration parts of the application into its own tool, otherwise we will need to hold on to old versions of things forever.

On the topic of the security vulnerability: As far as I'm aware, classifai uses H2 only in embedded mode, so the Console isn't active, therefore it isn't directly affected by it. We still should update, but it isn't quite as urgent.

Thank you @treo for your explanation, now I understood the issue. I will put this task on hold first and will seek your advice again when we come back to classifai backend.
