Upgrading Drupal

Hello Drupalers!

I'm using Drupal in my company for a year now, we have few websites running, and I'm questionning myself on how to maintain/upgrade a Drupal website.

I've searched in the forum, but I couldn't find a clear answer.
If you have one to provide, please post it/the link to it here.

So, let's say today I just finished developping my Drupal website, with all the functionnalities I want now, content types, blocs, pages, roles, etc., in other words, a running website. I put it in production, and users are registering and start adding contents, comments...
Two months later, I want to add the functionnality "if user have value XYZ in a new CCK field in his profile, he's allowed to access a new page I just created".
So I develop the functionnality in my development environment, it's working, but now, how do I put my upgrades in production?

Until now, I was creating the field manually from the user interface (back-office), exporting/importing the page/view manually and uploading my modified files/modules through FTP.
But I really don't like the manual actions (configuration). These may have a lot of security issues, like if I make a mistake creating the field (i forget to set it to required for example, i mistype the field id, i forget to put the edition/viewing rights), then this can lead to severe problems.

I am currently running drupal core version 6.16 and I would like to upgrade to 6.26. I have followed the guide in the update.txt and when I try to use update.php I get an Internal server error saying that the page that I am trying to access does not exist. I have tried to edit the settings.php to allow for update_free_access = TRUE but it does not change anything. Do I need to do some of the security updates in order to upgrade?

hello all,
I have an existing site in drupal 6 and I need to rebuild the same in drupal 7. I experiencing some problems with content migration from D6 to D7. I tried with node export module with Drupal var export format and CSV format but both did not work.
Is there any other approach to migrate all the contents from D6 to D7? Any reference or tutorial to use migrate module for content migration would be helpful.

Any solution for this issue will be really appreciated.

Hello Everyone

I am having some issues with a Drupal site i have taken over, The previous developer didnt do any maintenance or updates to the core & modules.

Now my problem is im trying to upgrade the drupal core to the latest verion of Drupal 6.x as thats what it's base is. I can get as far as putting the site offline & switching templates to a core template. When i try set the theme to a core theme (Garland or Marine) the site vanishes & im left with a white screen.

When I update modules they disappear from my site. Sometimes it leaves the module folder, but it will be empty.

This happens when I update modules and run update.php. [I am on Drupal 7.14 currently]

If anyone has any ideas why this might be happening, I would appreciate the help.

We have drupal 5.3 site uses the audio module as a major in our functionality, but we need to upgrade our site into drupal 7. Do we need to upgrade drupal 6 and then drupal 7 or directly into drupal 7? Seems there is no audio module for drupal 7, and also not stable in drupal 6. Is there any alternate module similar to audio module functionality?
Also some of the other modules available in drupal 5.x is missing in drupal 7 such as image,rolesignup.
