Migrate your sccm server to a newer server
After several years of use, it is necessary to migrate the SCCM infrastructure to one or more other servers. It is possible to migrate the server to another server or to migrate role by role. If the infrastructure remains the same, the first solution is preferable because it is faster. In the case where the roles are redistributed, it is preferable to use role by role.
It’s very important to verify the supported version of SCEM for the target operating system. In the case of Windows Server 2016, at least SCEM version 1806 is required. The name of the new server must be identical of the source server. The version of SQL must be identical on the source and on the target. Do not join the target machine to the AD domain at this time.
Configure the server with an ip address and a temporary name. Install SQL Server and ADK (the same as the target).
