Looking for assistance with vCenter...I inadvertently updated ESXi on my 2 hosts to 5.0 U2 from U1 before I had a chance to update vCenter to 5.0 U2.  Anyone have any suggestions or advice on what I need to do?  Should I just go ahead and update vCenter and move on?  I don't seem to be having any issues but still concerned on this oversight.  Thanks.

If you're going to update vCenter it may be better to upgrade to vCenter 5.1 since there are many features such as no more vram that 5.1 gives you.  You always want your vCenter to be at the same level or higher than you're ESXi hosts.

Ok...but if I wanted to stick with 5.0 for now...is it safe to go ahead and upgrade vCenter to U2?

Ok...also...why does VMware recommend vcenter updates before esxi anyway?

The reason you update vCenter first is that the older version of vCenter may not recognize the newer version since it's the vCenter that is backward compatible with the older ESXi hosts.  If you upgraded to a major build instead of an update it may have caused your vCenter to lose connectivity to your hosts.

Ok, gotcha.  So I got lucky with just a U1 to U2 update then.  Thanks for your help!
