> Yes. When you have a sectarian conflict, the only lasting solution is moving people around. Hateful people don’t learn to stop hating each other.
Jammu Division is an entirely separate ethnic community (Pahari) from that in Kashmir Division (Koshur).
Even during the worst of the partition and the Indo-Pak Wars, the mountain areas where active fighting was occurring never saw the same kind of religious violence you'd see in neighboring Kashmir or Punjabi speaking areas like Jammu City or Mirpur City.
This would be solving a non-existent problem, as the leadership making decisions for conflicts on or around the LoC are not from these regions.
And btw, the Indian and Pakistani army did attempt that when my grandmother was a child, but it didn't stick and people from one side or the other would just cross back - and this was the norm until the 1980s.

There are ways to resolve the problem longer term, and that requires forcing professionalization of the Pakistani Armed Forces and cajoling India back to the negotiating table using the carrot and the stick. Similar precedent already exists with the Israel-Egypt peace accords under Sadat, and would have happened under Bajwa, Nawaz Sharif, or Musharraf if they weren't undermined.
