That's not an easy one, it's like merging two standalone bigips. Synchronization doesn't support merging configuration.

 

i would take the road of the scf and try to verify the import :

 

on first machine 1) save sys config file -> save configuration to files 2) copy file and archive to second machine ons second machine 3) load sys config file <> merge verify 5) if ok remove verify to merge, then save sys conf, if needed remove all on ltm/sys related object from the scf 6) re create the cluster and synch from second
