Migrate config to new F5 Appliance

Daer, Please your recommendations. I have migrate configuration from F5 appliance in version 11.2.0 to a new model F5 appliance, both are only LTM. The new F5 have two version, 12.1.3 and 13.1.0.

 

I have considered configure manually related to the network, interfaces, vlan, self IP, HA and only load the base.conf file to new F5 containing the LTM configuration, so do not have problems with the interfaces since they are different.

 

What do you recommend doing to migrate the cofig? Thanks.
