vSphere 4.1 upgrade is almost finished

With five ESXi servers left to upgrade, I'll be completing the vSphere 4.0 to 4.1 this coming Sunday. This will make 29 ESXi upgrades to ESXi 4.1 Update1. vCenter was upgraded to 4.1 Update1 and a month after Update 2 was released, we upgraded vCenter to Update 2. Update 2 resolved an issue with editing the settings on a template.

I did experience one issue in this upgrade, and that was that  vCenter stopped updating the performance data. This happenned about two weeks after upgrading vCenter Server from 4.1 Update 1 to 4.1 Update 2. And, and it took approximately one month to get it completely resolved. The KB's for this are on a previous post. For us, we had to re-create the views within the database before it was completely resolved. This was the first time I had experienced this issue.

We've already upgraded VMware Tools on three clusters, and will finish upgrading this within the next month or two after all the ESXi servers are upgraded.
