It is a complex case. I am using GAE and already having users. Needed to
change the database
structure, so I need to move to new GAE app. The simplest option is to
re-invite the users but they are 100s. They will need to re-register again
using email/password. Probably not big deal for them but I try to eliminate
this step - if it is possible to migrate their accounts, then re-direct the
domain to the new GAE app and when they access the new site, which will
look the same they just have to login. But the ID's are used in the
database for their membership. If their ID's are different it will not
work. I am using the native GAE models for speed. web2py - only the auth
functionality plus the generated ID's.
