Where to download 7.0.0??

I'm currently running 6.1.6. I see where to download 7.0.2 but I don't see a download for anything before that.

Can I just upgrade directly to 7.0.2? If not, where can I download the previous versions?

Since you'd be using the migration module to update, Dolphin 7.0.2 will work just fine. Make sure you read the related documentation, as well.

Awesome. Where exactly can I download the migration tool and proper upgrade instructions for going from 6.1.6 to 7.0.2?

The migration tool is a module built into dolphin 7.

You must keep your D6 site as it is and install D7 into a subfolder where your D6 site is for the migration to be done. The site can be moved later to the root of your site later. This allows you to make sure things work and keep your D6 site operational at the same time.

Instructions are located here.
