Hello,
due to some network changes in my org I will have to add a second vCenter to the vCAC environment and migrate the Hosts and virtual machines, which were created up until now, to it. Basically I want to do this:
I've currently deployed vCAC in the form of a distributed installation.
Now I want to add a second, Appliance-based vCenter in another network segment and the following challenges arise:
- The ESX Hosts which were hosting the vCAC VMs would have to be connected to and managed from the new vCenter, there would be no configuration changes at the hosts directly. I assume this could be done in the following steps:
- take old vCenter offline, also stop vCAC services
- deploy new VCSA with the same DNS name but different IP as old vCenter
- disconnect the hosts
- reconnect them to the new vCenter
- rebuild inventory (folders, cluster etc.)
- (re)connect this new vCenter to vCloud using the vSphere Agent (the vCenter IP Address changes, but it would retain its DNS name, the DRS Cluster name would stay the same too), so I *guess* the agent would just reconnect to it and there would be no need to create a new vSphere endpoint.
The question is - could it really be that simple, what am I missing? How will that affect the inventory information in vCAC? Will the VMs be still recognized and reachable by the tenants after a data collection? Or is all the information lost during the transfer, when a the agent-vCenter connection will have to be re-established?
- In the context of the above, is there a need to transfer data from the old vCenter Database to the new one? That would mean a migration from MS SQL to Postgre. The permissions and Inventory structure are relatively simple, I could recreate it by hand or just use Inventory Snapshot to recreate the environment. Performance data and events are irrelevant. A potential problem would arise here - when the inventory (Folder structure, Clusters, dvSwitch etc) is recreated, will it still be recognized by vCAC, but that I mean after the compute ressource data collection?
- There is also an Orchestrator instance connected to the first vCenter, I would have to connected the second one to it too, vCO workglows are essential to the functioning of the vCAC environment. I don't expect problems here.
Thank you for any input!!
