Syncing F5 APM Policies Across Cloud Regions or Datacenters
 In a previous article, I discussed the syncing of F5 ASM policies across BIG-IP instances stretching separate datacenters or different cloud regions. This use case was extremely useful to me when dep...

Amolari, thanks for the feedback. Yes, you are correct.
Understanding policy sync device group setup for Active-Standby pairs To add devices to a device group, all devices must belong to the same local trust domain. If you want to sync access policies with a device that does not belong to the local trust domain, but also belongs to a Sync-Failover group, you must reset the trust between the devices and remove them from the Sync-Failover device group. (For more information, see BIG-IP® Device Service Clustering: Administration on the AskF5™ web site located at http://support.f5.com/.)
After you establish device trust between your BIG-IP system and the devices, you can add them to a Sync-Failover group again.
