We are currently trying to migrate a Firepower 2130 model managed by FDM (7.2.6) to FMC, but we keep encountering an unknown error.
We have added a test box to FMC and are using FMT (Version 7.0) in "Migrate Firepower Device Manager (Includes Device and Shared Configurations) to FTD Device (New Hardware)" mode to upload a backup file obtained via API.
After uploading the backup file, we selected the following features:
- Interface
- Routes (Static)
- Platform Settings
- Access Control
- NAT
- Network Objects
- Port Objects
- Access Control Policy Objects
- Migrate Only Referenced Objects
However, when we select "Start Conversion," the following error occurs:
Blocked
cannot unpack non-iterable NoneType object
How can we resolve this error? We've tried changing the selected features and removing the flexconfig portion from the backup file, but the result is still the same.
