How to move uv's without ruining material

Support Materials and Textures
1

So I got a mesh that needs some manual tweaking. Problem is whenever I move my uv’s there’s a line that appears cause the uv’s are no longer properly aligned.

Is it even possible to move textures in a direction cause its in the wrong spot without making seams appear form the slightest movement?
