• You are upgrading a redundant K2 SAN. This means you have two K2 Media
Servers (primary and backup) that take the role of media file system/database
server.
NOTE: If the K2 SAN has multiple K2 Media Servers, you must upgrade all to the same
version.
If you are upgrading a basic K2 SAN with multiple servers:
1. Upgrade the server that takes the role of media file system/database server first.
2. After the media file system/database server is upgraded and when instructed to do
so in a later task, upgrade your other servers.
If you are upgrading a redundant K2 SAN:
Use the following steps to manage primary/backup roles and upgrade your two media
file system/database servers in the proper sequence. This avoids triggering a failover
event.
1. Determine the current primary/backup roles of the servers. You can use Server
Control Panel (via the K2 System Configuration application or on the local K2
Media Server) or NetCentral to make this determination.
2. Shut down the backup server.
3. Upgrade the primary server.
4. Continue with upgrade tasks on your two K2 Media Servers that take the role of
media file system/database server. If you have additional servers, upgrade them
later, when instructed to do so in a later task.
