Our current environment is vSphere 5.0 with 2 datacenters, each with its own vCenter 5.0 servers and ESXi5 hosts.
We are looking to upgrade to vSphere 5.5 but have been warned that moving to 5.5 from 5.0 may be tricky. So, before we do anything else, I'm looking for USER advice on upgrading ver5.0 to 5.5. I've found in past upgrades that formal recommendations from VMware are fine but I get the best suggestions from Users
Any Gotcha's to watch out for?
