Thanks for you links, they are very helpful. I thought that I was running 5 on the old vCenter but I was actually running 5.1 build 1123961. However, I am not able to find the "Actiion" menu on 5.1 to export the vDS for some reason. Is there a trick on how to do get this "Action" menu?
So both of my vCenter servers are at the same level, that should make the migration a lot more easy with the export and import option. Just that I am not able to get that "Action" menu.
Thanks,
