we have used Invista 2.1 to migrate off of 3 CX600 arrays onto CX3 and CX4 arrays. The 2.1 code has a number of gui related issues and we are planning the upgrade to 2.2.

for the most part, Invista performed well doing its Data Mobility moves. I had one Virtual lun that faulted numerous times during a Data Mobility session and I think it was because it trespassed on the Source Clariion side.

I am looking for any feedback on anyone who has performed a Production Invista upgrade process from 2.1 to 2.2 and their experiences with the process.
