Sorry if this is old news, but we just got on a new dedicated server, and it's stuck at v2.55. Our old server had 2.64, and some of our settings didn't make it over in the move.
Please point me in the right direction for upgrading to 2.64. We're running Redhat with an Ensim control panel.
Upgrading is mostly just a matter if installing 2.64 on top of 2.55.
The only minor issues I know of are
making sure DB_File is installed if you want to use bayes. 2.5x didn't need it, 2.6x does
making sure that if razor is present it is newer than 2.36, or is 2.36 with the taint patch applied.
Be sure to read the top README in the tarball for a few more odd-and-ends in the way of upgrade issues.
