Description of requirements/features: Hello,

I have a database from website that I need to move to wordpress.

The columns and tables from old database is different from wordpress schema.

I need an expert that understand the wordpress mysql format, since they use a lot of wp_post table and store almost everything there.

I have a few scripts and mysql views to help the migration, but they are incomplete.

- The person will have access to phpmyadmin to work.
- We will run the views and scripts
- We then need to fix the issues.

Extra notes:

Tasks:
- Old news categories will be new tag

- Products on old website is separate table, new wil be store as posts.
- Old categories products will be subcategories of products.

- I have more than 5.000 free subscribers to import. And like 900 articles to import (WP woosubscriptions plugin)
