I need to move a light switch a few centimeters because a built-in wardrobe is going to be installed

Description:

I need to move a light switch a few centimeters because a built-in wardrobe is going to be installed and right now it's in the way. The switch works fine, I just want to move it so it's accessible and doesn't clash with the wardrobe. I would like the installation to be left properly finished and without exposed wires. I would appreciate it if someone could tell me whether any chasing needs to be done or if the existing wiring can be reused.
