If I understood it correctly, you want to repoint your linked clones from vcenter to another vcenter, if this is the case, it is not officially supported by VMware for linked clones/Instant clones because your linked clones will work as long as vcenter hostname and IP address is same. If in case IP or hostname changes, you have to recreate linked clones Otherwise they be in error status in view admin page.
You can copy your full clones VDIs from one vcenter to another however linked clones/Instant clones won't work. The only option is to recreate them.
There are 3rd party blogs to achieve it however not officially supported hence I would not recommend you to do in production.
