Here is the method I’ve found works best: Chisel out the tile as normal, and peel off the plastic layer of the Ditra. Scrape off as much of the felt as possible. If your subfloor is OSB, don’t go back over it with Ditra, since you can’t guarantee a good bond after grinding.
Can you Retile over DITRA?
A coat of concrete admix or bonding liquid (latex) the day before, will ensure old and new will adhere. Schluter doesn’t recommend using latex modified thinsets over Ditra and under porcelain tile.

Can you install Ditra over old Thinset?
You can put new thinset on top of old, but only if the old thinset is perfectly smooth and level. Use a floor grinder and pass it back and forth over the old thinset until it is perfectly smooth and level. You can now tile directly on top of it as if it were a new surface.
