symposion_app/ROLLING OVER.md

Export any reports you want to keep.

Take a database dump.

Remove all accounts, tickets, invoices, talks, etc. I used the commands below, but this may be simpler to achieve by selecting the relevant users in the Django Admin, selecting "Delete" and letting the cascading deletes deal with it.

Replace USERNAMES_TO_KEEP with an array of staff usernames.
