Upgrading Drupal

Most things are working fine after upgrading from D5 to D6 but a few pages are giving me this error

Fatal error: Unsupported operand types in /home3/site/public_html/includes/common.inc on line 1582

I've seen a few posts from D5 but nothing recent and nothing with the same line. Any thoughts?
Thanks.

We had an old drupal install which had custom content, but I'm not sure which type it was (either a custom content type or whether it was in a blog, page etc). It has 4 db tables and from the home page was a link '?q=project'

Hi,

Is there a module that could help me migrate the data from profile fields into taxonomy fields like this?

I've googled around this question for a long while, but couldn't get any decent information. And I'm sure many people would love to see a decent solution to this issue (hopefully through an easy-to-use module). So if you have any ideas or suggestions please reply!

The issue:
I have a small 2-year-old social-networking community site (set up with 5.2 and now upgraded to 5.20) with over 500 registered user profles. The profiles are handled through a combination of core Profile module, Bio (for the long biography field) and Usernode (to construct views listings). But most importantly, each user has filled out fields like Country, Town, Activities, Interests which link the users together. That linking of users is probably the most important data that my community site has, and I would loose the site if I loose that data and functionality.

Cheers guys !

I read about upgrade topics, this is my particular case is as follows.

- Three years ago I install Drupal 5.1 from Fantastico in a local hosting company, and upgrade these installation to Drupal 5.3 (upgrade with Fantastico-Drupal wizard)

- Yesterday I change my webhosting to another company (Bluehost.com), but Fantastico Bluehost has Drupal 6.14, so I upload Drupal 5.3 to Bluehost, install and upload my oldDB. It works !

- Now I want to upgrate my Drupal 5.3 to 6.14, also disable all external modules when backup.

Hi guys,

everything is in the title
I have this huge database that i want to use to install a local copy of the website, do you know which tables I can clean up to have the smallest sql file as possible?

thanks

We have the drupal sql dump, drupal settings.php file and not much else from an old drupal installation. I.e. the installation files are missing (includes/themes etc).

Is it possible to convert this into a working Drupal site using current version?

Cheers
