Drupal 6.x

Im upgrading from 6 to 7. I followed the instructions found here: https://www.drupal.org/node/570162. When I get to step 13 Run the update script i get the following error:

Fatal error: Call to undefined function drupal_add_html_head() in /var/www/clarityraoupgrade/includes/install.core.inc on line 713

Any ideas what to do?

Recently I inherited one very old and outdated durpal6-site and I have to "revive" it. I'm looking at it, and honestly do not know what to do. It is some old D6-site, with 6.28 core and ~50 equally outdated modules. I think first step is to bring it to the latest 6x version, then I will try to upgrade it to 7x.

Q1: Should I start first with core, then modules? Or first modules, then core?

Q2: Can I upgrade core/modules right to the latest version (core to 6.38), or I have to go over all versions in between?

Hi All,

We're trying to migrate an old Drupal 6 site with tons of custom content types over to Drupal 7. Needless to say, this has been a very difficult process.

I do not actively use Drupal so i am not certain what are the correct terms to explain this issue.

There is a content type ( say xyz )

and I have created content within this xyz content type.

Say i have created 60 instances ( or pages of separate/unique contents within xyz content type).

However When i go to the site and click on mydrupalsite/xyz , it does not list all 60. In fact just 8 only.

I'm doing commerce websites [link removed] but when added to about 7-8 module and activate up to be white screen on Aministrator.Khi -> Site building -> Modules also similar errors.

I use Drupal version 6.19
Can you help me solve it? Thanks!
