PLM, Vantage 8?

If you have the PLM module and Pro E/Pro Cam/AutoCad.. how good is this
document management for revisions etc..? We are currently on 6.0.519
looking to upgrade to latest and greatest. But I would like to hear
from a company that has Epicor Vantage 8 installed with PLM module..
Thanks, (Also, how hard is the DIY on the upgrade and
installing/setting up the modules) I am new to Epicor Vantage, I came
from a QAD background..
