Reconfigure Manager on Firepower Module in ASA 5506-x

[a.elflew]

I have a Firepower module in my ASA 5506-X and had registered it with my FireSIGHT Management Center. Unfortunately I removed the device from FireSIGHT Management Center and hadn't removed the manager from the Firepower module first. I also realized I failed to document the registration key I used for the initial registration. I tried re-adding the manager to my Firepower module on my ASA and I am now getting the message:
 error

 Active Peer  x.x.x.x already exists

Hi,

Delete the existing Manger and then add again with new registration key.

Configure manager delete

Configure manage add x.x.x.x key
