Migrating Vmware datacenter to another network
Posted on 2013-12-25
I am in the process of migrating my entire network from class C /24 to a Class B /16 totally changing IPs.
In my vmware infracture I have a VNX3150 Datastorage in one cluster, one vcenter server with 3 host and about 10 bussiness critical VMsThe migration of the VNX seems very straight forward once I have a new vcenter. I use ISCI which is in a separate network that I am not planning to touch at all.
I thought the migrating the ESXI was a straight fooorward task as well. Removing Hosts from Vcenter changing Ip of the hosts and subnetmask rebooting creating a new vcenter (which I can afford since is very small datacenter) with new Ip addressing and Voila rejoing host to Vcenter and life is good!!!
After a conversation with Vmware they seems to believe I need to rebuilt my entire datacenter from scratch, rebuilding ESXI from scratch and rejoining storage and recreating networking switches and connections. The question is is it true? do I have to go to the painful task of starting from 0?
I alrady have enough moving DControllers, PC and all kind of equipment..HELP!!
