Upgrading Drupal

I was trying to upgrade from drupal 5.x to drupal 6.15) .

At running update.php step, had a unrecoverable error;

user warning: Table 'mydomain_2inhomemedical.menu_router' doesn't exist query: DELETE FROM menu_router in /home/mydomain/public_html/2inhomemed/includes/menu.inc on line 2346.
user warning: Table 'mydomain_2inhomemedical.menu_router' doesn't exist query: INSERT INTO menu_router (path, load_functions, to_arg_functions, access_callback, access_arguments, page_callback, page_arguments, fit, number_parts, tab_parent, tab_root, title, title_callback, title_arguments, type, block_callback, description, position, weight, file) VALUES ('node', '', '', 'user_access', 'a:1:{i:0;s:14:\"access content\";}', 'node_page_default', 'a:0:{}', 1, 1, '', 'node', 'Content', 't', '', 4, '', '', '', 0, '') in /home/mydomain/public_html/2inhomemed/includes/menu.inc on line 2443.
...

(the error messages went for about 600 lines actually).

I believe I was following the steps as it's listed here: http://drupal.org/node/340073 .

1. I checked (using the update status module) and upgraded all the drupal 5.x modules to their latest 5.x versions before going on to the drupal 6.x stuff.
2. Then took a backup of the files and database.
3. Logged into the site with the user 1 account (made the site 'off-line' )
4. Switched the theme to Garland

I have just upgraded our site (on a test copy) to Drupal 6 from Drupal 5 and many important pages are giving 404s. Examples are /admin/user/roles and admin/user/permissions. These are both missing from the administration menus and give 404 errors (themed 404s) when I try to navigate to them directly. We're also missing pages that should be available for the modules I've reinstalled such as /coder and /admin/panels/panel-pages (and their menu items).

Hi everyone,

I have a question, it may be too dumb to you. However, I'm a bit scare when reading all the problems related to upgrading Drupal to the newest versions (of the same Drupal 4, 5 or 6). I understand that a site should be upgraded to the latest version.

I don't know how this could have happened, but on my last upgrade one of my content types went missing. The content is still there but the content type is not in the content type list, therefore making it impossible to add or edit content. Any help on this would be seriously appreciated.

I recently upgraded to Drupal 6 from Drupal 5. (It was, unfortunately, very painful). I am still trying to work all the glitches out. The main being my menu system. We are running the domains module. Each domain has it's own of the following tables:

Hi, please excuse a possibly confused question from a complete newbie - I have just upgraded from version 6.13 to 6.15 and also installed various module updates. I now have two issues:

1) I get the error messages below which I frankly don't understand:
