Hi,

Coming from Django world, I do like the simplicity of automated schema generation and maintenance.

However, I can imagine that slightly more complex projects would need a bit more flexibility.

How can one go about changing the database and migrating the current data? For example, if we want to change an existing ENUM, how do we use a mapping function to convert the old to the new format?

Is there any way to tap into the schema generation code and perform anything custom or is SilverStripe simply not intended for more complex projects?

Nothing is built in for those complex style migrations of content. There has been a developer discussion about implementing better migrations in the next major release (https://groups.google.com/forum/#!topic/silverstripe-dev/niQhqfK-h44, Django even gets referenced :))

It's something that would require someone to 'own' the development of. If you have experience in that area and the need, would be great to get a plan of attack together.
