Upgrading Drupal

1. This was whilst trying to upgrade from Drupal 5.1 to 5.2 .. I retain a full db backup of the database before the upgrade
2. I uploaded the new drupal 5.2 tarball and ran the update.php
3. I then moved the installed modules from the /modules folder to sites/all/modules folder and the themes from the /themes to the sites/all/themes/ folder

So that was what I did, and now quite a lot of modules seem broken down..A lot of blocks dont work and none of the Module settings menu entries in the admin pages dont show up anymore..
The default theme wouldnt come on...but actually came on when (and after) I visited the Theme settings page..
All the modules show up in the modules page and in the admin pages (while browsing 'By Module')
Besides these, A lot of enabled blocks don't show up properly...and the Events module doesn't seem to be around anymore (No Events Calendar).

So, I've a panicked a bit after that... I tried restoring off my old DB backup, and with Drupal 5.1 itself (off a fresh tarball, but with the non-core moduels and themes moved to /sites/all ...But that ran into the exact same problems as above.

I tried restoring with the same old directory hierarchy (installed non core modules in the /modules folder itself ...and that wouldn't work either... Running into the same first problem indicated.

I have an old PHP app that I very slightly integrated with Drupal on my site. Mostly I just want the user authentication and permissions stuff to make the app only available to certain users. The app is located in a subdirectory under the main Drupal dir, which is the root of my website. So when people go to www.exmaple.com/recipes they get my recipes/index.php file, which has this code at the beginning:

I've upgraded my main site from 4.7 to 5.2 with few problems.
However, I wanted to try out the new wonder-theme Garland. I've selected it and made it the current default theme. But when I go into the "configure" page, the entire section for "Color scheme" is missing. On another site on another box, it's fine.

I checked the file download setting as mentioned in an old Beta forum topic. It's Public. Permissions for the files directory are 777. I'm a bit lost as to where to look.

Would it be possible to make an upgrade from 4.6.5 to 4.7.7 at once? Or what steps should i take in between? Probably 4.6.11?

I don't think i've ever had a trouble-free drupal upgrade in my very vanilla setup, and this was no exception.

This time, image paths were all wrong (after upgrading drupal, and images and img_assist).

URLs were being generated like:
www.mysite.com//usr/local/share/drupal/files/pictures/pic.jpg

The files table of the database was similarly mucked up.

I have upgraded 4.7.7 to 5.2 drupal core successfully. Now I am working the modules, one at a time.
