To import to WSN Links from any mysql table you can try this process:

1) Using phpmyadmin, alter the names of each field of your old data table to match the equivilant WSN Links field names. Set all fields to NOT NULL as well.
2) Remove any extraneous left-over fields.
3) Export the data from this with complete inserts.
4) Import this data to your WSN Links table.

After importing data directly to the database, it's neccesary to regenerate the counters. Click 'regenerate counters' in your WSN Links admin panel and run the regeneration for all links, categories and members as well as regenerating totals and your category selector.

If you can't import your database, you can hire database import service at the standard WSN services rate (see the site's services section).
