You must upgrade when the user’s activity is lowest and in shortest time. You must minimize the time period when the Advanced Authentication DB Master server is upgraded and not the DB Slave server, because replication of databases that do not sync can break the DB Servers.To perform the update, perform the following steps:
Create snapshots for all the Advanced Authentication servers.
In the DB Master Server, open the Advanced Authentication Administrative Portal and switch to Updates section.
Click Update to apply the OS updates.
Click Check for updates and then Update to update the Advanced Authentication Server.
In the top menu, click an administrator's username and select Reboot.
Repeat steps 2-5 for the DB Slave Server and Member Servers.
WARNING:You may get different errors in the Advanced Authentication Administrative Portal sections on non-upgraded servers when DB Master is already upgraded. Ignore the errors and do the upgrade.
NOTE:With the upgrade, a DB Master server changes to a Global Master server in the default site, a DB Slave server changes to a DB Server 1 in the default site. Member Servers change to Web Servers.
