Upgrading Drupal

I have a 4.7.1 and a 4.7.2 site that I need to upgrade to 4.7.5. I assume there are only two ways to accomplish this:

1. Apply patch for each upgrade version to the newest (i.e., 4.7.1 -> 4.7.2 -> 4.7.3 -> 4.7.4 -> 4.7.5)
2. Copy over existing 4.7.x sites with new 4.7.5 site, then copy back over required old files.

From user experience, which method is the best?

Also, how do I find previous Drupal upgrade patches? Where are they archived?

Thanks!

I have a new project to upgrade an old drupal site to a current version and I wanted to get some advice from the community.

I don't know what version of drupal I'm working with - it doesn't say on the system.module file. Only - $Id: system.module,v 1.103.2.1 2003/11/09 01:22:16 dries Exp $

Upgrading from Drupal 4.6.9 to 5rc2

installed new files
corrected settings.php

...all as usual

go to run update.php, get a blank page.

What am I missing? =)

I've just experienced a really BAD fatal error while attempting to update my Drupal 4.7.4 site after uploading the newest Advanced Poll module (I think it's the Dec.30th, 2006 version). I have full backups, but before I go and upload a huge database and replace the entire root directory of the webserver, I thought I'd ask here first.

Here's what happened. I took the site offline, verified that it was offline with a regular user from another machine, and then navigated to update.php while logged in as administrator.

I saw the update.php page come up, I had just completed a full backup, so I ran the updater. It came back with a page full of modules and their associated pop-up menus, but they all said "update not needed", or something like that. I pressed the go button anyway, just as I've always done before when seeing this page.

This time, I was greeted with a white screen and the words:
Fatal error: Call to undefined function: drupal_valid_token() in /usr/local/websiteroot/update.php on line 685

Prior to botched upgrade I was running 4.7.4. Attempted to upgrade to 4.7.5. Ran the update.php script and got the following:
