General

FMC migration script "sf-migration.pl" changes the model_numer post migration. Which leads to other issues like licensing and ability to form FMC-HA with peer.

Symptom

FMC model number ( Hardware model) changes post migrating config from backup FMC to Target FMC via migration script sf-migration.pl E.g: Source (backup) FMC = FMC 4000 Target FMC = FMC 4600 sf-migration.pl was invoked to migrate from FMC 400 to FMC 4600. Post migration the model_number of Target FCM (4600) was changed to FMC4000 at May 9 14:49:31 UTC 2020] Using MODELID=F [Sat May 9 14:49:31 UTC 2020] Using model path /usr/local/sf/etc/model-info/66/F [Sat May 9 14:49:31 UTC 2020] Saving F and /var/sf/.modelpack/model-pack-6.5-7.tgz to flash [Sat May 9 14:49:33 UTC 2020] Running VAR:ims.conf:/etc/sf/ims.conf [Sat May 9 14:49:33 UTC 2020] Changing values in //etc/sf/ims.conf [Sat May 9 14:49:33 UTC 2020] Changing HWSERIES to 3 [Sat May 9 14:49:33 UTC 2020] Changing MODELNUMBER to 66 [Sat May 9 14:49:33 UTC 2020] Changing MODEL to "Cisco Firepower Management Center 4600" The change can also be observed in FMC GUI: Help > About

Conditions

Using migration script "sf-migration.pl" to migrate config between 2 different FMC model versions.
