Upgrading Drupal

I'm upgrading a site from 4.7.x to 5.x. I want to convert to book type nodes to story type, How I can do that?

I recently upgraded a site to Drupal 5.1 (from 4.6).

It wasn't smooth but I did manage to work most issues out. The one thing that just won't go away is the grey line between the top nav and the content table:

http://www.festivusbook.com/

I'm totally flummoxxed about where this line came from. I went through the "style.css" for my theme and changed every border to dotted, but that particular line stayed solid. (I changed the dotted borders back).

Where the heck is it coming from?

I upgraded a site to drupal 5.1 for the express purpose of implementing Captcha and somehow or another the captcha admin pages are inaccessible to me.

The rest of the site appears normal, but when I try to go to "http://www.example.com/admin/settings/captcha" I get this error:

Hi,

I am trying to upgrade my 4.7 custom module to 5.1.

Based on the instructions in the Handbook I have changed my code under hook_view in order to show my custom fields.

The problem is, that when I use a code as suggested in the Handbook:

    $node->content['my_field'] = array(
      '#value' => theme('mymodule_my_field', $node->additional_field),
      '#weight' => 10,
    );

then nothing is displayed in the node preview. But when I just skip the theme function, like that:

In drupal 5.x (and a 1and1 account), I got clean URLs to work ok, but it is buggy.

For instance, I click on a button on the menu and get this url:

http://www.website.com/drupaldir/node/1

if I click the same button on the menu, the url gives me this:

http://www.website.com/drupaldir/node/node/1 (which is wrong)

And if I click again :

I am still in 4.6 and cannot migrate to 4.7 now because of lack of time.

I tried without success to use the Project-module-v4.7 in spite of the example given in http://drupal.org/node/36051.
There is too many differences in the API of 4.6 and 4.7 (http://drupal.org/node/22218#handling-of-return-values-from-callbacks) : the downgrading (v4.7 ->4.6) is too hard for me.
