I have a client on v12.0.41311.996 SP6.2. They are finally wanting to upgrade. Maintenance has been in place the whole time, so they are covered there. I was wondering what the steps would be? Looks like 12.x to 14 was backup, uninstall, reinstall, then restore. Then to 15 was the same. Could I just jump from 12 to 15.5? I will probably take a full backup first and then do this on a new disk so I can go back if necessary. Thanks in advance.
