Migrating stats from WordPress.com blog to self-hosted WordPress.org blog

It’s possible but requires help from an official WordPress support person (aka “Happiness Engineer”) to do it:

As for stats, they can also be moved, but staff have to take care of that. Once you have Jetpack installed on the new WordPress.ORG install, post the relevant URLs in this forum thread and then add the “modlook” tag n the column on the right.

* Note: “WordPress.ORG” above really means “self-hosted” site. That’s a common misnomer that was introduced earlier in the quoted thread.

So to do it from start to finish:

  1. Migrate your site to a self-hosted install as much as you can.
  2. Install the Jetpack plugin and connect it to a WordPress.com account. (I don’t know if it helps if it’s the one associated with your WordPress.com site. It can’t hurt.)
  3. Open a new WordPress.com support thread. Tag it “modlook” and request that they move your stats to your new domain. Make sure to provide your old WordPress.com site and your new self-hosted domain.

Alternately, you can always use the paid “Guided Transfer” that also includes moving stats.
