Is platform migration required between big-ip 4000 and i4600?
We are about to migrate from a pair of BIG-IP 4000 to a pair of i4600. We want to upgrade from the source version 12.1.0 to 15.1.2 at the same time if possible, therefore we aimed to use this as a basic procedure: https://techdocs.f5.com/en-us/bigip-16-0-0/big-ip-system-migrating-devices-and-configurations-between-different-platforms/migration-of-devices-running-different-version-software.html However in that procedure it says the interfaces has to have the same names in the source and target devices, and that is not the case here. The source device is using interface 2.1 and that is not available in the target device. I guess the "tmsh load sys ucs <filename> platform-migrate" is required in this case, right? If so, can we still go from 12.1.0 to 15.1.2 and still use the basic procedure above but with some platform specific changes?
