Here VEP 6 is running flawless on DP10. DP users are really lucky to enjoy the MAS version of VEP . I'm on mac platform and that's mean to override AU multi midi-channel limitation (better than VST3). I hope that our Logic mates could soon to get AU3 VEP features... ;) 

Brian posted in motunation a couple of advices about VEpro MAS migration proceeding:
*deselect in preferences>plug-in tab all VE pro AU versions and select just MAS versions (I also reverted to Pre Gen mode).
*use remap midi devices function and change old event input midi output to new MAS multiport VE pro instances
That's all.

Great news! 

Great!! Is there estimated time arrival of this update.?

1400?….my God!!!!!!!
..I just have 400

are you speaking about how long will take to load the project in CUbase and if this time is delayed due to lot and lot of VEP midi ports instances?
With respect to this question I have found that the same midi-VI template load a little more in Cubase 7 respect to DP 8. I explain this because DP is a cocoa native app and better optimized for mac than Cubase: I don´t think is due to excessive VEP midi ports. This load time is insignificant compared with the time that take to load all sample libraries into the VEP server instances

In Cubase you won´t use Event input, instead you´ll use multiport VST access, remember: in just one VEP pro instance you have available 16 port*16 channel (no more AU 1port*16 channel limitation). In this way if you put in groups your instruments (Play, VSL etc..) to fill all ports in each VEPpro server instance, you´ll optimize CPU thread with fewest instances.

OK!!! I´ve found out the problem Recently I installed 32Lives. This app is a new a bridge for 32 bits AU plugins (and VI) in 64 bit host DAW. But what this app make is a copy of native 32 plugins in a new "resurrected" 64 bit format. In fact these new "resurrected" plugins appear together their 32 bits parents in the same plugin component folder. Once I deleted these resurrected copies and do a clean installation of VEP the problem was fixed.

Yohhoo!! Is not mac/Cubase/VEP user there with the same problem???

That´s the first time that I´v seen a problem with VEP since I´ve used: VEP quit suddenly when I exit the application. This problem has happened once I upgraded to Cubase 7.5 and I downloaded the last VEP update. Have anyone seen the same problem?
