Do we have to change the region of the apple id if we move from one country to another ..What if we didn't change the region after migration we still use the services like apple music in that migrated country without changing the region .. why is the change of apple id region option available?
Changing the region assigns the correct App Store and iTunes Store for purchases. If you change banks you will need to change your Apple ID region. Certain apps only work in a particular region too so there could be an issue with that as well. This link provides much more information - Change your Apple ID country or region - Apple Support
