Yup, I searched the full tag and replaced it with the new full tag or removed. All according to the upgrade documentation.
And if I do a new install on a new server, and then restores a copy of the database, I get problems with the passwords.
To do a migration to a new server I can:
1) Install YAF on a new server.
2) Configure it as a new install and use the same Administrative Password. (Install password, the one in app.config)
3) Make sure it runs.
4) Restore the database to the one I want to migrate.
5) Run the /install/default.aspx and change to the restored database.
Am I correct on this?
