Maybe you've used 'Force offline' instead of 'Force to Standby' and the upgraded member came back 'Offline' and 'Disconnected'. The 'Disconnected' part is okay, because it can't sync between two members not running the same software version. 

I would just check if a 'tmsh load sys config verify' looks okay and check the results of 'tmsh show sys mcp-state', on the upgraded member and bring it online again.
