I believe in v10.x there is an option under System | Platform that specifies whether a unit is part of a redundant pair or standalone. I would:

 

  1. verify no vlan/gateway failsafe or HA groups are configured (remove if configured) - System | High Availability
  2. disconnect all cables on standby unit aside from management interface (including failover cable, at which point units will go active/active)
  3. change each unit to "standalone" - System | Platform
  4. validate that no network failover configuration remains - System | High Availability | Network Failover
  5. power-off and move unit 2 to other DC

Hopefully they won't remain separated for too long, Murphy's Law being what it is...
