Importing profiles

Has anybody had experiences with importing profiles into D7, either from sql files or csv files? I am importing business listing profiles, and have had a hard time with the sql db crashing after the import. I think there may be an issue with the password/salt fields, but I am unsure.

Any other experiences with importing?

if this is not so big SQL file - you can just import it via web interface (phpMyAdmin). Or, you can use SSH too.

hello
1. Compare all dolphin's fields with your imported file (you can insert profile info with md5 password)
2. Need update all your profiles (add salt)

for example : @see data migration module - BxDataMigrationProfiles.php
