# Preparing for future updates

Massive Dungeon works a lot with databases to speed up your workflow but it's easy to lose it during an update if you work on the original database. For that reason, this will work with composite databases and is easy to use.

1. Go into MassiveDungeon/Data
2. Duplicate DT\_DemoPaintPallet and DT\_DemoLight and rename them. (It's crucial otherwise, Massive Dungeon will not see them. **Every name must be unique**).

3. Open CDT\_AllPaintPallet and **add** your new DT\_PaintPaller duplicate to it
4. Open CDT\_AllLights and replace the current DT\_Light in it with your duplicate
5. Keep your duplicate in a folder outside of MassiveWorld in case updating overrides the folder.

While you're at it, you can also remove the demo content from the CDT database (once you are comfortable with Massive Dungeon).
