Upgrading from Drupal 4.5.x to 4.7.x is not much of a pain really, in
case you use core modules only. In fact I devoted a big chunk of my time
around christmas to fix bugs in the 4.5 -> 4.7 upgrade path. The core is
ready for you to upgrade from 4.5 to 4.7 directly, there are specific
functions to help this migration. Drupal.hu still runs on 4.5 and is
going to get an upgrade to 4.7 soon. Thanks to the work put into the
upgrade system, the data migration is just a click of a button. Of couse
we add new stuff to the site and reorganize existing functionality, and
that takes time. Also if you use custom modules, you need to invest your
time into it, but core supports the direct upgrade nicely.
