does all glue have to be removed before laying ceramic tile?

Question:
does all glue have to be removed before laying ceramic tile?

Choices:
yes
no

 

Glue from what? What's the glue on, slab or wood underlayment or subfloor (not underlayment)?

Only if it's loose or might come loose. Eight years ago we were tiling our Kitchen and the vinyl floor which was there just seemed to fuse itself to the concrete slab slab. It wasn't budging. So we scored it and cleaned it and tiled right over it. Eight years later you wouldn't know there is this vinyl floor beneath it.
