Hello,

I’m using nexus community edition 3.77.1-ubi (docker image) in my prod environment now i would like to upgrade my nexus to the latest version 3.84 since my organisation has planned to get a nexus pro licence. I have planned to test the upgrade before implementing it in prod while on the process i encountered the following,

- Current db config in my nexus is H2 and pro only supports postgres so i wonder if there will be any dataloss while migrating db.( NOTE: I have a s3 blob store to configure my artifacts).
- I read in the docs that nexus pro provides a db migrator tool for migration but in staging/dev how can i test the migration ( can someone shed light on this pls?)
- Can i use my pro license in staging env to check the migration and then reuse the same licence for prod?

Thanks in advance.
