Hi;
We are migrating from vSphere 4.1 U3 to 5.1. (We are only going to 5.1 due to the model/age of our Host HW)
We have two production ESXi Hosts in a Datacenter/Cluster on a physical vCenter 4.1 server, with only 10 server VMs. (These 10 VM's are
accessed by about 5000 local users)
I have a Third ESXi host that I installed v5.1 on, and set up vCenter 5.1 on a VM using the Simple install.
I setup the V5 Datacentre/Cluster and vDist Sw, and I feel I'm at the point where I can migrate.
(All ESXi boxes have 6 NICs and 4 FC HBA's. Two NICs on each are for VMkernel, and the other 4 are uplinks to the V4.1 vDist switch.)
The hosts are such that they can handle the load as each Host is upgraded and the VMs vMotioned back and forth.
I don't really have a way to test the migration, and I'm wondering how best to move the Hosts from the old vCenter 4.1 to the new
vCenter 5.1. VMFS version would be upgraded later.
There's no problem with segmentation as they are on the same network and VLAN.
Any words of advice?
Thanks.
Gregg
