Versioning should not be an issue. Applications written in a previous version of notes should "just work" in newer versions.
Encryption/access control could be an issue. Local replicas are by default encrypted to the userID that created them, and Access Control on a database is enforced. However, if you were just moving from one laptop to another, I would assume you also moved your ID file and are logging into Notes as the same user who created the replicas previously?
Then there is the error message about Autosave. Try turning off autosave in the File>Preferences, Basic Notes Client Configuration, top left. This may/may not worked. Since this is the error you are getting, it sounds like this is where the problem is. Either something in the database is telling your Notes client that an autosave needs to be restored, or something in the Notes client thinks that it needs to restore an item (due to a previous client crash, etc.).
If you can get past this autosave message, and assuming you have the proper ID to get past the encryption/ACL, then the database should open for you
