NetBackup upgrade:- 7.5.0.4 to 7.7 or 7.7.1

Hi There,

We are planning to upgrade our enviroment from 7.5.0.4 -> 7.7 or 7.7.1

What are your suggestions (should we go 7.7 for now or 7.7.1) and how good you guys are going with 7.7 or 7.7.1

Please give me your options and suggestion and an overview on any problems encountered.

Much appreciated.

Thanks.
