Hi Everyone,
I am looking for some guidance.
We have a small datacenter in a region running VCenter on a Windows Server 2012 version is 5.5U1, there are 2 ESXi hosts running 5.5 U1, they both replicate to a Vsphere replication appliance running on a third ESXi hosts on 5.5 U1 (VA is 5.8.0.1 Build 2170514)
There is no HA setup, we are running Essentials so we are planning on some downtime.
We need to upgrade the ESXi hosts at least to 5.5 U3 because of a problem we encounter where a virtual server is stuck at Loading https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2092807
What would consider the best approach:
Upgrade vcenter to 5.5U3 then all the ESXi hosts (eventually upgrade later VA)
Upgrade vcenter to 6.5 a then all the ESXi hosts (eventually upgrade later VA)
Or another scenario
Would VA work at it scurrent version if i upgrade vCenter and ESXi hosts?
