we are migrating our sites into DNN4 from some non-DNN sites. therefore, we have 50,000+ users with username and password from the old site which must be imported into this new DNN's database. let's say we have all the necessary parameters, and for passwordformat we are using 'clear'(plain passwd store in DB), is that possible just to do a bunch of insert statements into all user related tables for these 50000+ users?

what tables should have data insert: i identified about 4 aspnet_* tables and 1 Users tbl and 1 UserRoles tbl. i added respective info in all 6 of these tbls but when using the username/passwd to logon, it fails.., what exactly did i do wrong?

please advise.
