Upgrading Drupal

Hello all, i want to upgrade my local drupal 5.7(with more then 700 nodes) to drupal 6.0, i already searched the forums here and the faqs and i cant find a tutorial how to do it :(

hope somebody can give me some info :)

Hi all,

I'm in the process of upgrading a site that used Drupal 4.6.6 to Drupal 6.0. To try and ease the process, I've upgraded most of the modules we used to drupal 6.0 (and will finish doing so either by converting myself or converting the code to use a contributed module by the time the site relaunches) - however, my question concerns the core set of modules which have gone through significant changes. Does anyone have any ideas on how to upgrade the database tables to the new structure?

Good Day,

Upgrade RC4 to Official release. Copied new files as instructed and tried to run update.php resulted in page not found. Did a fresh install and typed in site.com/update.php still resulted in page not found.

Any Ideas?

Thanks you,

Mark

I have searched forum and was unable to find any relevant information. Please forward me to any helpful topics that you may know of, thanks =)

Scenario

A town I live in, with a striving art community, was aiming for a local art Social Network. A friend of mine took the initiative to start the project (long before I knew him). He successfully acquired city grants (as much as 12 thousand I think) and mass Community support. The initial problem, however, was finding someone to complete the website for this project. The city recommended a local company. Not knowing of anyone else capable of handling a task this large, he hired them; Nothing expensive, they were only $140/hour. He didn't know any better.

Problem

I've followed the instructions (made a backup of the installation and db), disabled modules and themes, and put the site in offline mode.

When I load update.php, and before I start the actual upgrade, I get the following:

Hi,

Perhaps a silly question but..... Am I right in thinking if I upgrade to Drupal 6 I will lose a lot of functionality from the modules I use that are not yet compatible with Drupal 6?
