Restore from UCS archive to existing BIG-IP system in a redundant pair.

Hi,

We have a pair of BIG-IP devices for redundancy. I've backed up our BIG-IP configuration to a UCS archive, and now plan to do some work on the system, one BIG-IP device at a time. The backup is in case this does not go to plan.

I see K8086 for "Replacing a BIG-IP system in a redundant pair without interrupting service", but I am not replacing either device, I'm keeping both and possibly using the UCS archive to restore the device to a good configuration of itself if there are problems.

Is there any knowledgebase for this, or is K8086 the closest thing, and if so, which steps are not required?

Version is BIG-IP 11.5.4.

Thanks
