Ben, Adding to what Victor wrote... the complexity really depends on how complex the site is. It isn't necessarily so difficult. You need to go to the project page of each and every contrib module and scour it for info on upgrade issues.Since D5 is so mature -- there is no shortage of information. Just invest the time on those project pages and you should be golden. Shai On Fri, Oct 17, 2008 at 2:47 PM, Victor Kane <victorkane@gmail.com> wrote:

1. Backup your site first. 2. Perform the upgrade on a test site first

The upgrade process itself (upgrade to latest 4.7.x before upgrading to Drupal 5.x) is safe and well documented.

1. http://drupal.org/node/36996 (Introduction to upgrading) 2. http://drupal.org/videocasts/upgrading-to-5

You might, however, run into problems with modules you might be using, so you should read up on their 5.x state, and the upgrade problems others might have registered in the issue queues first.

Hi,

I would like to migrate a web site from Drupal 4.7.2 to 5.10 (specifically 5.10-1~bpo40+1 from Debian etch-backports).

I imagine this migration might be quite painful, does anyone have any advice?

I'm wondering whether I might be best to start with a fresh Drupal installation and semi-manually transfer the data from the old database using a script.

Thanks

Ben
