@jorenvh1 Thanks for raising this issue.
Do you know the old and new values of engine_version?

[jorenvh1]

@ewbankkit Ah right, that's the issue. Well, since I'm using aurora serverless I tried to change the engine version.
At first it was: 5.7.mysql_aurora.2.08.3 in my tf config but every apply it would say that it couldn't find a valid upgrade path from 5.7.mysql_aurora.2.07 to 5.7.mysql_aurora.2.08.3. I thought I made a mistake in the engine versions since there are also serverless specific engine version. I tried 5.7.serverless_mysql_aurora.2.08.3 this one as well as just 5.7. Really confused on what TF/aws expects here.
