If you are referring to the corrupt db issue your safest bet is to back up your appdata and just update. If you run into the issue restore from backup. The truth is, the longer you wait to update the more likely you're gonna run into issues. This is because in major updates there are gonna be database changes and the db needs to be migrated to the latest version. Sometimes this can cause issues especially when you have not been keeping up with updates. There has been many updates to radarr since this issue and the more you wait the risk is higher that they updates includes more upgrades to the db. And because you're now so far behind the migration of the db has a higher risk of failing. So just get it over with already IMHO. This goes for all software updates btw, keep backups and update regularly to avoid issues in the future. Yes, sometimes updates has issues, but you're gonna have even more issues later on if you don't keep up to date.
