removing ftd from fmc query

[Vishal6]

Hi All,

Does de-registering/removing ftd from existing fmc and re-registering into new fmc would flush the configuration from ftd or it retains its configuration when i add into new fmc.

Also if configuration has been flush from ftd, then would it stores in existing fmc so i can take backup and load it into new fmc

Upon de-registering the FTD from one FMC and registering it with another FMC, the configuration will be wiped clean. To address this:

1. Manual configuration is required for device-specific settings such as interfaces, routing, DHCP, etc.
2. Shared configurations like Access Control Policies (ACP), NAT rules, and Intrusion settings can be transferred using the Import/Export functionality.

Please note that the 'Import and export device configurations' feature was introduced in Firepower version 7.1.
