This question already has an answer here:

I have a brick wall that I am trying to add a door to. I have already UV mapped it, so when I move the loop cut to the right height, it distorts my UV map. How can I avoid having to unwrap it again? loop cut

Press G, G or Ctrl E > Edge Slide to move the loop cut. Then in the bottom of the Tool Shelf or by pressing F6 turn on Correct UVs.

  • $\begingroup$ Also the inverse of this operation, once you've baked everything, you can remove the extra loops again using 'x' then 'g', this should preserve the UVs. Now your higher poly model once again becomes your low poly model. All the baked textures will still match up so long as you keep watching the UV coordinates and use 'Undo' should you ever damage a UV island when removing a loop. $\endgroup$ – MarcClintDion Oct 18 '14 at 1:14
  • $\begingroup$ You can also use this technique to push loops up against each other and use remove doubles to merge the two loops. This helps with cases where the previous method fails. $\endgroup$ – MarcClintDion Oct 18 '14 at 1:15
