interesting, which way around is that? do we also drop the old one there?

Yes, definetly drop the old one. In osmo-pcu is even more complex because we first lookup by TBF, and then the assigned MS object, but sometimes the MS object has non-yet-known-imsi. So at some point, when figuring out the IMSI, we figure out we have a duplicated MS object and we need to move gained information from the previous MS object and then drop that MS object plus its related TBFs.
