Replacing a server/profile manager etc

Hi there,

We have 20x 21.5 iMacs (late 2013) - they are used for training courses. One of them was setup as the server and had profile manager installed and configured.

Unfortunately, THAT particular machine was knocked off a desk and smashed. We are about the receive the replacement via insurance.

My question is, what would be the best way to re-setup the server and profile manager?

Each individual iMac is a member of the same iCloud account (I can see them all when I login to my Apple ID online).

Previously, when I added each iMac as a member of the server it downloaded two files:

mdm_profile.mobileconfig

Trust_Profile_for_Infomed.mobileconfig

Will the client iMacs now need disconnection from the current environment and adding to the new one after it is completely configured?

Unfortunately I didn't have a backup of the server although I am not too upset as it was setup to be messed around and tested with.

Many thanks for any guidance,

Jack
