Hi Team

is it possible to do so?
if yes please share me link or steps to the same

You cand find old binaries in the releases page of the repos, e.g.: https://github.com/brocaar/lora-app-server/releases. I don’t think there’s a way to gracefully downgrade as the data models differ a lot, so it’s up to you to backup whatever you need and rebuild the DBs.

As for documentation, requirements, etc., I guess you could check the docs repo and try to match commits by date to the versions you want to use.
