Migrating ESX 4 and 3.5 hosts to new vCenter Server 4.0

Jump to solution

I am setting up a new vCenter Server 4.0 with an Oracle database to take the place of two vCenter’s that use the included express databases. They are both well over the recommended 5 hosts and 50 vm’s for the express database, oops.

The first is vCenter 4.0 that uses the included express database is on a Dell 1950 server. The ESX 4.0 hosts are on 2 clusters on Dell blade servers that have 5 blades per cluster and are using EqualLogic iSCSI storage arrays for the datastores. Plus there are a few individual Dell R900 and Dell R710 servers using local storage connected to this vCenter.

The second is vCenter 2.5 that uses the included express database running on a Dell 2950 server with like 20 other Dell 2950’s running ESX 3.5 using local storage.

Looking for a little insight and advise migrating hosts to the new vCenter Server.

Thanks … Jim Hurley

I would say the easiest way would be to create new new vCenter Host OS ( I would choose 64bit which will get you within the requirements for 4.1). Once the new vCenter Server is online, I would then install a standalone license server for your VI3 Hosts, then start disconnecting and removing the hosts from the other environments and into the new.

Stand alone license server can be found

Welcome to the Forums - It all depends on whether you want to maintain any information from the previous environments - if not then build the new vCenter server remove the existing hosts form the old vCenter environments and add them to the new environment -

This document should also provide additional information -http://www.vmware.com/pdf/vsphere4/r41/vsp_41_upgrade_guide.pdf particularly section 5
