After changing certificates on vCenter the SRM and vSphere replication 9.x plugins will show "Not Accessible", may also show up as "No Healthy Upstream"
Existing 8.x Plugins in environment will not be updated for the new vCenter thumbprint and will override the current plugin connection after reconfiguring through VAMI interface
Plugins can be verified by going to Administration > Client Plugins. VMware Site Recovery will be listed twice and one of the plugins with be the 8.x version and one will be 9.x
We will need to remove the 8.x plugin package from any vCenter that is in linked mode.
