Question concerning UserID's

[leebo]

Hello,

The company I work for is currently looking to migrate our forum from vBulletin 4 to Xenforo. Before we migrate however I need to verify that the "User ID" numbers will remain the same. We currently have a custom App that allows users to login using their vBulletin Username (and UserID) that MUST remain the same during the conversion. If these numbers change during the conversion users will be unable to access their data inside of the App.......a major issue for us.

Yes there’s an option when importing to retain content IDs. This includes user IDs.

Awesome as that’s a MAJOR issue for us.

Are the passwords hashed the same way as in VB4? If not, what algorithm is used (we have a custom script to verify user credentials against the database we will have to migrate). Also, what does the database schema look like for the user table?

The 'user table' is actually several tables. xf_user_authenticate has three columns for user id, authentication scheme (ones are included for various importers) and a final field for a serialized string for data appropriate to the authentication scheme.

We support multiple authentication schemes, including those in vB so the passwords will still work. They’ll be updated to our much more secure hashing method when the users first log in.
