User migration question

[billpratt]

We have started using v3. Part of the sign in process is to migrate a user from our old system into our new. When the user logs in for the first time, we validate them in the old system, inform them of our new security, require them to enter something on a form and then migrate them over. With the current state of v3 I dont see how this is possible given there is no control over the login functionality using an implicit flow. Any ideas or suggestions would be greatly appreciated.

Have you seen these samles? Look at the EulaController. I believe this might fit your needs (partial logins).

I did not see that. I'll check it out and see if it will fit our needs. Thank you!

Those examples were exactly what I needed. Thanks!
