import content types from sql dump
Assuming your SQLite dump is complete, your best bet is probably to try and properly convert it to MySQL format and then restore to an empty database.

There's a good thread over at stackoverflow with information on SQLite to MySQL conversion: https://stackoverflow.com/questions/18671/quick-easy-way-to-migrate-sqlite3-to-mysql

I would paste a solution from there here, but as it's a sibling site, probably ok to just pop over and try some of those solutions.

Good luck
