Best way to start fresh?

Hi all,

I am almost completed doing testing with Dolibarr.

I created fake companies, invoices, bank accounts, expenses and such.

When I am ready to go into production, should I use the purge/delete all files in directory function in the admin tools section, or should I scrap and reinstall dolibarr with fresh db?

I am happy with the settings, just want to remove the fake entries and start over with real clients.

Regards
