Is it possible to upgrade directly from a 7.x environment to 10.x? This is a small setup with a single tape library and only 3 servers getting backed up. I have checked out the upgrade portal docs and its just alot of info. I was curious since due to how small the setup is if its just as a simple as running the 10 installer and it will upgrade since its not a very large setup.
I would just start over but our requirements mandate we keep a full year of tapes and i was hoping to not try and do some sort of migration of it all.
It seems doable; but if I were in your position, I would choose to take some steps.
Whatever version you choose to go, these are your friends
