Vitaberry (200)
This mod is a rework of Vitaberry (200). So if you are coming from VB (200), you can just remove the old mod and replace it with this one. You shouldn't lose anything.

Vitaberry (5000)
If you don't care about losing all Vitaberries, seed and crops. You can just replace the old VB (5000) mod with this one.

If you want to move a bit more smoothly and keep already gathered berries/seeds, you can follow this guide. (Crops will still be lost when removing the old mod).

1. Add this mod above/before (higher priority) the Vitaberry (5000) mod in your GameUserSettings.ini. But keep also the VB (5000) mod enabled!
   
2. Have a look at Change Stack Size to make the berries/seeds have the size you want to.
   
3. Have a look at Info: Conversion Structure / Function. It will tell you how to convert VB (5000) berries/seeds into the ones from this mod. Caution: Make sure you have at least the same stack size configured for this new mod then you have for the old one or you will lose items while converting!
   
4. Remove the old VB (5000) mod.
   Or you could also wait some days/months and then remove the old mod. As long as you keep the mod order all new berries gathered will be the new ones.
