Hi,

I am scoping a migration of data which may, due to parameters out of my control, involve migrating data from a post-1.9.1 release into a database set up for 1.9.1.

Were there any data schema changes between these version that would cause problems for such a migration?

Thanks.

It's very difficult as a lot of things were changed, including Membership, Profiles and field encodings.

Basically you can do it if you know how YAF works and by custom sql scripts. I doubt that anyone will have a possibility to log in.
