4. This way you'd easily get your 15000 members imported to your new site. For those 2000 members already existing can be restored from the backup you made.

Thank you for trying to help other members, but if you are not 100% sure, then it is better not to respond.

This suggesting will for sure break your board. You can not simply copy single tables from 1 database to another, this will for sure break functionality.
