I´ve 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 doesn´t know about my new servers.
I can unreg and reg them against my new primary and they get going but it´s a lot of clients.

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

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