Few days ago from the post date, Dariusz Falkiewicz and I had to move a MySQL database folder to a different location on the same server.
We worked on Ubuntu Server v12.10 and had to move MySQL v5.1.41.

It sounds good, it could work! Later we realised that moving MySQL default folder is not so easy as it appears.
