1. For each .sql file, use SSMS → Tasks → Export Data... → select your database → filename should be the same as the .sql but with .csv, Destination: Flat File Destination, Unicode → Write a query to specify the data to transfer → paste in the contents of the .sql file
2. Open the .csv files in your favorite text editor and re-save them as UTF-8 with no BOM.
3. Copy the .csv files to /var/www/discourse/script/import_scripts/ on your Docker instance.
4. Edit the specific to TDWTF section if you are converting a different Community Server forum. The data is 'community server section id' => discourse category id for any categories you have already made on Discourse.
5. Copy communityserver.rb to /var/www/discourse/script/import_scripts/
6. Run the following command in your Docker instance:
   (cd /var/www/discourse/script/import_scripts/ && RAILS_ENV=production sudo -E -u discourse bundle exec ruby communityserver.rb)
7. You have now migrated your Community Server forum to Discourse.
