I built a nether portal in my castle near spawn (77, 140, 434). In the nether, I destroyed the original portal as soon as I teleported (0, 84, 71) & moved the portal to y lvl 5 to created a nether subway. New nether portal is now at (-10, 5, 69). I go through the new nether portal and it will NOT link to the original Overworld Portal and keeps making a new one (-97, -38, 562). I destroy the newly generated portal and go through portals again and just keeps generating the same portal (-97, -38, 562), even after I destroy it. I’ve tried breaking the portals and re lighting, it still generates the new portal (-97, -38, 562).

How do I link the original portal with the new nether portal and vice versa
