Importing from vBulletin 3.6.8


Active member
Finally purchased XenForo and trying to convert my vBulletin 3.6.8 forum to Xenforo.

I first click "Import User Groups" and get these errors :(

Server Error

Any ideas please?

Thank you!

P.S. I cannot upgrade to vBulletin 3.7/3.8 since my license has expired.

I'm not sure if there are any database schema changes between vB 3.6 and 3.7.
Most likely there are looking at the error.

The importer officially only supports vB 3.7/8.

Is there any reason why you can't upgrade to 3.7/8 before importing?

I cannot upgrade to vBulletin 3.7/3.8 since my license has expired. I only have access to 3.6.8. :(

Is there any workaround?

Unless you can upgrade to 3.7/8, or 4.x, not really.

I'll mention it to the developers though.

Edit: It seems there are quite a few changes from 3.6 to 3.7 so even if this error was fixed, the likelihood of others is fairly high. Really the only solution is to upgrade your vB installation.

I managed to upgrade to v3.8.x :LOL:

The conversion finally worked.

P.S. Nice to see a fellow Londoner on here :)
