Pre-requisites for SEP upgrade:

  1. Enable local authentication on SEP Manager Console. You can create local login credential in SEP manager console. That account will be replicated to replication partner server (if you have).
  2. Remove any replication partner in the SEPM primary server before the upgrade.
  3. Space required for SEPM upgrade: 3 times the DB on disk. Have around 50GB of free space on the drive where SEP is installed.
  4. Take a clone of the SEP server before the upgrade as a safety measure.
  5. If you have two SEP Manager server, you need to first remove the replication partner, upgrade them separately and then you need to add them as replication partner in the SEPM console.

This completes the upgrade. If you have another SEPM server and that is replication partner with the primary server then upgrade that SEPM server with the above steps. Once done, re-add the secondary SEPM server with the primary SEPM server as replication partner.

That is it.
