When adding existing ASA to a rebuilt FMC

Hello,

 

We have an HA pair of ASA 5525 with the firepower module.  The FMCv was corrupted and we had to take it offline.  The FMC has since been rebuilt and we are ready to add it back as the manager of the firepower module. Everything I've read so far describes a net new install of an ASA to an FMC but from trial and error I've experienced once you make the FMC the manager it wipes out the config of that device. Can this be avoided or will i need to recreate the config on the FMC first and push it to the ASA after I make the FMC the manager?

If you have backup from old, restore to new FMC with new version, suggest to re-register the device, until the config is pushed its not going to overwrite here.
