- Create the bond at the OS level with only the second interface in it. Use a different network from your current sync network.
- Change the cluster object's configuration on the management server to use the bond for sync. Remove the old sync interface from the cluster object's topology table.
- Push policy.
- Remove the IP from your old sync interface at the OS level.
- Add the old sync interface to the bond.
This process should not cause a failover, as you have working sync at all times. Still, assume there will be an outage at some point.
