Hi,
You can't sync between different versions (so make sure they're in sync before the upgrade), and it's not a supported config to run on different versions, but I have just verified that the newly upgraded unit on v10 will stay in standby mode with the serial cables connected, and I expect it to go active once the other unit is taken offline.
So, yes, your procedure should work fine. I have not tested this scenario without the serial cables though (using network failover).
