Data evolution

Data evolution

With development of the CultureHub naturally come evolutions in the data model.

MongoDB evolutions

Those evolutions are recoded in the model-evolutions.md file. Most of them are written so that a simple copy-paste is necessary, but make sure you read them carefully beforehand to see if there's not something that needs to be adapted beforehand.

Also it is a good idea must to make a backup of your database before applying any of these migrations:

mongodump -d culture-hub
