Upgrading Drupal

I've gained quite a bit of drupal experience over the last year and we now have some 1100 sites running on drupal (most of these hosting other peoples content, about
50 of them with stuff that we wrote ourselves). After playing around for a bit with drupal 6 I figured I'd try to do an upgrade of a minor site to see how the process works
in practice (as opposed to the theory), and let's just say that I'm underwhelmed.

While there exist many excellent pieces of writing concerning upgrading drupal from one version to another (major or minor) in practice it seems that life is not that simple.

As long as you stick to core modules and themes it all seems to work quite well, but hardly any site is built using only core stuff.

Specific issues that I'm running in to are:

- there is no simple way to check if all the modules / themes a site uses are supported by the new core version other than going through all the listings manually and trying to trace down which modules have their functionality implemented in different places and store their data in different spots (cck field permissions is a nice example of this)

Hello! I have a russian installation, so some terms a translate back.
My site was upgraded from 5.10 to 5.12 for couple days ago, but i forgot to run "update.php". So, today i was working and saw: for anonymous user all materials (nodes) not shows (access denied), views says "There is no materials to show" on front page "Welocome! Site just installed etc...". All checkboxes in User Access are in their own places (like before upgrading). Under uid=1 (how i'm working) all works correctly: all nodes are shows. Unauthorized users can see links to node in my php-snippets in blocks.

Hello there,

Hello,

Tried to update my drupal site at 5.11 to 6.6 and it went through all the steps now I am looking at only a white screen with no content.

Tried to run the update.php script and get this error:

Fatal error: Maximum execution time of 30 seconds exceeded in C:\Inetpub\tchspeakers\includes\database.mysql.inc on line 155

Fatal error: Maximum execution time of 30 seconds exceeded in C:\Inetpub\tchspeakers\includes\session.inc on line 56

Fatal error: Maximum execution time of 30 seconds exceeded in C:\Inetpub\tchspeakers\includes\session.inc on line 14

Here's a list of files changed by the latest Drupal upgrades. We use this so we don't have to replace the entire Drupal installation, as usually only a few specific files have actually changed.

Files Changed by Drupal Upgrades - simply select the list pertaining to your Drupal installation.

Cheers,
Alex

I have tried a number of times to install the security upgrade 6.6 on a test site. I believe I am following the upgrade instructions correctly, but after I run update.php the status report still tells me I need to update the Drupal core. I am replacing all the files in my directory with the upgrade except the sites directory. Does anyone know what I'm doing wrong?
