Before you upgrade the management server, you should temporarily disconnect the partnership with all management servers that are configured as replication partners. If a replication partner launches replication during the upgrade, it may have unpredictable results.
Disabling replication is not the same as permanently deleting the replication partnership. If you delete the relationship and then reinstall the management server, the management servers perform a full replication instead of an incremental replication. See Deleting sites.
You must log on to Symantec Endpoint Protection Manager and disable replication at a minimum of two sites.
To disable replication
In the console, click Admin > Servers.
Under Local Site > Servers, expand Replication Partners and select the management server.
Right-click the management server, and then click Delete Replication Partner.
Repeat this procedure at all sites that replicate data.
Restoring a replication partner when a site has already been replicated
After you upgrade all management servers that had a replication relationship, you add the replication partner back. You must also re-add the management servers that were configured for failover and load balancing.
You only re-add replication partners on the computer on which you first upgraded the management server. The upgraded management server must also have previously been a replication partner in the same site farm.
After you add the replication partner back, Symantec Endpoint Protection Manager makes the databases consistent. However, some changes may collide.
