I had a vCenter server vCenter02 with 6.5 version(recently upgraded from 6.0 to 6.5).
After upgraded, i have installed new vcenter(VCSA02) and added to the existing domain(SSO) for linked mode. After completion when i connect to the Old vCEnter server(vCEnter02).
i am not able to see the new vcenter server under inventory as below.
but when i connect to VCSA02 vcenter(new vcenter), i am able to access the both the vcenter servers as shown below.
When i checked the system configuration from VCSA02, i am able to see both the nodes active state when i connect from VCSA02.
But when i connect to old vCenter(vCenter02), under the nodes its showing as degrade state.
Note: Both i have logged in with vsphere.local administrator account only,
What might be the cause of issue and why its not showing both the vcenter servers.
