Risks of restoring a db backup made in an RU5 to an RU8 instance?

I have a instance running RU5 and I’d like to restore one of its backups into another instance that is running on RU8… basically bringing information from Test into Dev… they are not on the same server though.

Is there anything I should look out for or a best practice for what I’m trying to do here? I appreciate your input.
