Migrating SEPM between servers

Hello,

We recently purchased new servers and will be moving SEPM 11.x over from our old server to the new server. My question is how do I go about doing this without orphaning the users, and just making it as simple and quick with as little down time as possible.

We want to keep the same settings, packages, etc. but we do not want to have to reinstall SEP on every system (currently 35+).
