I am working on a migration to a newer virtualized server. The old one has Apache 2.2.4 according to the old servers phpinfo(). The new one with the most up to date has 2.2.3 . How can this be assuming no trickery is involved? The old one is years old.

Alot of the guides I reference use apache2 in folders names and many of the conventions. The newest version of things, as I understand it is called httpd. Did apache change the name from what it originally was? (i.e. break the web server component into its own project called httpd, I realize the original daemon was probably still called httpd)
