We encountered an issue upgrading our forum directly from SMF 2.0.18 to 2.1. The site displays a vanilla forum with no existing data. What's the recommended procedure to upgrade and ensure data integrity is maintained?
what have you done to do the upgrade? it sounds like you did not follow the right process.

It looks like a fresh install rather than an upgrade. The link posted above contains all the necessary info on how to perform a large upgrade.
As answered, it sounds like you did an install, not an upgrade.
Hopefully you have a backup of your original database.
Restore that and then follow the instructions that illori linked
