Vmware 5.0 to 5.5 general failure

[healersart]

I am currently upgrading VMware 5.0 to 5.5.   I have 4 host and 1 of them I am upgrading from 5.0 to 5.5.  After I did this, it seems like I am trying to rejoin the newly 5.5 host with older 5.0 so that I can transfer my VMS, but its not connecting.

You guys know if anything about vmware 5.5.0 host can live on vsphere 5.0.0?

Welcome to the Community,

if you are managing the hosts with vCenter Server, you need to upgrade vCenter first as an older vCenter Server version cannot manage newer ESXi hosts.

Are you upgrading a VMware vSphere ESXi host from 5.0 to 5.5 ? And after upgrade, are you trying add the VMware vSphere ESXi 5.5 to a VMware vCenter Server 5.0 ?

If the answer for the two questions is Yes, you will need to do what André said, upgrade the Vmware vCenter Server from 5.0 to 5.5 first, and then upgrade the VMware vSphere ESXi hosts from 5.0 to 5.5.

You guys are awesome... That answered my questions. Which also lead me no another question... Do I have to turn off my vm's to upgrade to Vmware vCenter Server from 5.0 to 5.5? or Can I do this live?

No, you don't need turn off your VMs to upgrade your vCenter Server... and if your ESXi make part of a cluster with vMotion enable, you can even upgrade your ESXi hosts without turn off the VMs, to do this just migrate the VMs to another host.

Unless something unexpected happens you can do everything with the VMs powered on. I assume you are just managing the ESXi hosts with vCenter Server, i.e. no other features installed (e.g. VMware View, SRM, ...)
