Upgrading from 2.2.1
Where can I find the FAQ on the upgrade process from 2.2.1 to 2.6.4

I wouldn't imagine there is one, as the assumption would be that upgrades are done sequentially.
I would recommend that you at least start by upgrading to 2.6 (although 2.5.6 is still available for download) and read the README carefully, then move to 2.6.4.
