I did check again and am running the original backup program in 8.2.4 that I have set up in a virtual machine.
CAVEAT: I don't have the new backup, which is generally set up via appointment with AC. I do not know if you lose functionality in the original AC backup after. I doubt it. I also don't know if it works properly. Haven't done a restore.
Once done with these test backup, I will test the restore.
