I am currently running zfd 6.5 sp2 , which was upgraded from 6.5 sp1, 6.5 ,5, 4, 3.2 ect...

I have had some odd issues over the years that I am not going to get into now. However I am wanting to go to version 7.0 and am wondering if i should do a clean fresh install vs another upgrade.

Anyone have any documentation on removing all existing policies and packages ?

Any tips or suggestions welcome.
