Ive been too fast when I replaced our primary servers.
I had 2 primary servers with old hardware that i want to exchange with 2 new devices (virtual).
Installed a third primary and made it first primary as described in documentation "17.2 Replacing an Existing Primary Server with a
New Primary Server"
Installed a fourth primary server.

Unistalled, deleted and shut down the two old primary servers.

Now, those clients that have been shut down during my update is lost, they doesnt know about my new servers.
I can unreg and reg them against my new primary and they get going but its a lot of clients.

Ive tryed to install the old servers again and import the old backed up certificate but the lost client says "No matching certificate".

Is there a way to modify the clients to understand that I have new primary servers.
