Thanks, this is very helpful. I have a list of items I need to research and one of those was how to import media from one cell manager to another, now I can cross that off my list. If I can import enough media to give me 30 days worth of backups into the new environment then I should be reasonably safe restore-wise when I go to DP8. If I get a restore request for something older than that I'll have my old DP environment around. But therein lies the rub, I would assume both cell managers need to be at the same level of DP if you were going to try hacking the cell_secure file to allow both to think the clients belong to them, right?
