Upgrade and hardware migration

I will be upgrading from 6.0 mp3 to 6.5.

I will also changing from a Master and a Media server to just a Master/Media.  The reason behind this is my Master server is quite old and the Media server is fairly new with a lot of horsepower.

Any recommendations.

I used to work with NetBackup all the time but now I have quite a few other resposibilities so I just do not feel quite as confident.  It looks like a should be coming back up to speed.

Thank you
