Default PCM after engine swap...CASE relearn???

I swapped an engine into my car. The only thing that has changed is the fact that the donor engine has a new crankshaft position sensor and is still using its old harmonic balancer. I did not change anything PCM related.

Do I still need to do a CASE relearn procedure?

Thanks!
