While in this potentially long and arduous process will I lose the ability to restore from the 10d tapes we currently have?
For instance: Joe User decided that he has screwed up a spreadsheet, and he does not want to reverse the changes. So he comes to me asking if I can restore from a back-up. Can I restore from a back-up if I am currently running version 11d or 12.5?
I have a limited window of time to do this.
Thanks in advance.
