Managing a SUSE Linux Enterprise (SLE) 12 client on SUSE Manager 2.1
Switching to the SUSE Customer Center is a prerequisite for managing SLE 12 clients with SUSE Manager Server 2.1
SUSE Linux Enterprise Server 12 and SUSE Linux Enterprise Desktop 12 are manageable after the migration.
You need to re-generate the client bootstrap script on the SUSE Manager Server to manage SLE 12 clients.
