Huh, do you mean Alpha 20 exp compatible with Alpha 19 stable?
It's always best to either A) continue playing at the Alpha 19 until you end your playthrough, or B) Start a new playthrough when upgrading between Alphas (major releases). Since they make a lot of changes when they go from Alpha X to Alpha Y, it's always best to start anew. When they upgrade from Alpha X.X to Alpha X.Y, you might be able to do so without a lot of issues.
To add onto this, deleting all of your 7D2D files manually (simply uninstalling the game sometimes fails to do this simple task) between every alpha before upgrading is highly recommended. IF you don't, due to merging files and files being placed alongside one another, it's most probable you won't be able to start the game at all.
