4100 with FTDv HA Pairs

[hurricane05]

Hi,
We have a few 4100 series appliances (6.7) where we have 3 to 4 logical FTD devices. The FTDv devices are configured in HA pairs running 6.7, where primary is on one 4100 appliance and secondary is on another 4100 appliance. We ran into issue where the secondary virtual instance in the HA pair has failed and will not start. So next course of action is to break the HA pair from within the virtual FMC and delete the logical instance from the 4100 chassis and rebuild.

Question is, what happens when you break the HA pair, will the existing primary virtual instance that is running keep all the current FTD configurations?

Thx in advance for any assistance given.
