Requirements for primary and backup servers

Certain License Server conditions must be met before license activation can succeed on a redundant pair. The primary server can have activated licenses at the time of pairing. However, the server you use as the backup cannot have activated licenses or any previous license activations. If licenses are currently or have previously been activated on the backup server prior to pairing, the License Server ID must be reset for the backup server before licenses can be successfully activated on the pair. See Reset License Server ID for detailed instructions.

You can configure a redundant pair with a primary server with or without licenses on it. When the primary server is hosting activated licenses and is managed by an offline License Manager, you must select the Sync button after pairing the servers. This will synchronize the existing licenses with the backup server and complete the pairing.

Note: The Pair Status in the Server Details Page will display as Pair not synced until you perform the sync action.
