So if you are developing a theme on server A, and you want to copy to server B, it's no longer just copying over the theme files, but also reconfiguring the modules.
This is time consuming and error-prone. Profiles are perfect for this, but building and maintaining profiles in wiki pages is time consuming. Now, thanks to the profile export, it becomes easier & faster.
For now, go to tiki-admin.php?page=profiles -> Export
And on the new site, tiki-admin.php?page=profiles -> Advanced -> Profile tester
