Repoint embedded PSC to a external PSC

[sajithru]

Hi All,

I have a lab environment deployed with a VCSA v6.5 and an external PSC. I need to add a secondary vCenter server v6.5 deployed on windows server 2012 with an embedded PSC to join the external PSC and enable linked mode between 2 lab environments.

As far as I know to reconfigure embedded PSC to an external one I need to have a replication in between them and replication can only configure during deployment of external PSC.

So since I already have my external PSC deployed how can I achieve this task. Kindly help me out.

Thanks in advance.

Thank you for your reply. I have looked into that but it's not my situation. I have 2 standalone vCenter environments with embedded platform controllers. I can configure replication partner with only one of the as per my knowledge so this method won't work I guess.

I was able to resolve this by following below mentioned steps. I have already reconfigured a vCenter(with an embedded PSC) with an external PSC.

1. First I backed up 2nd vCenter DB with embedded PSC.
2. Then I created a new vCenter VM with pointed to existing external PSC.
3. Then I restored my backup of VCDB into new vCenter.

I found out all the configurations and historical data was available after restoring backup. Both vCenters are now connected to external PSC. I have faced a vSphere HA configuration issue after restoring DB but sorted it out by disabling and re enabling vSphere HA.
