[PonyORM-list] How to deal with schema change ?

[stephane martin]

Hello,

i googled a bit before, but cant find good ressource about it, so....

How am i supposed to deal with schema change ?

Let's say i develop an app. In v0.1, i design some database schema
with db.Entity. Everything works fine, users are happy, and the
database gets some data.

Then maybe i'll have a feature request, and I will have to add some
field to some Entity. Or maybe i will need to change some field type
from unicode to datetime, etc.

What is most correct approach to migrate my data to the new schema ?

Many thanks and kind regards,
Stephane
