Upgrading Drupal

I'm in the throws of upgrading a site from Drupal 6 to Drupal 7.

I wanted to switch from Garland back to the theme I developed under Drupal 6, but there was a message saying that it was not compatible with Drupal 7. So I made some changes to it, which meant I could select it as the theme, but when I did this I got a blank screen. In the apache error log I get:

[Thu Nov 17 01:34:26 2011] [notice] child pid 19062 exit signal Segmentation fault (11)

which does not augur well.

I'm looking for some kind of SQL query or other code that will let me move taxonomy info from taxonomy_index etc. into the new taxonomy term reference field API tables. Has anyone else been able to do this? I haven't been able to find any info on converting taxonomies from 6 to 7 in a way that doesn't just leave them dumped in a Taxonomy Upgrade Extras list on the node edit screen.

Hello,

I am performing an upgrade of CKK after a succesfull upgrade of Drupal 6.22 to Drupal 7.9
Now there is one field in the section "Fields that cannot be migrated because some modules are missing." and it says:

Hi,

I upgrade Drupal 6.22 to 7.9. All went fine.
Now I am trying to upgrade CCK. I activated the desired modules and ran Migrate fields.
Then the following message appears:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=364&op=do StatusText: Service unavailable (with message) ResponseText: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'public://RCD.gif' for key 'uri': INSERT INTO {file_managed} (fid, uid, filename, uri, filemime, filesize, status, timestamp) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7); Array ( [:db_insert_placeholder_0] => 464 [:db_insert_placeholder_1] => 1 [:db_insert_placeholder_2] => RCD.gif [:db_insert_placeholder_3] => public://RCD.gif [:db_insert_placeholder_4] => image/gif [:db_insert_placeholder_5] => 161 [:db_insert_placeholder_6] => 1 [:db_insert_placeholder_7] => 1309873312 ) in content_migrate_filefield_data_record_alter() (line 229 of C:\xampp\htdocs\sites\all\modules\cck\modules\content_migrate\modules\content_migrate.filefield.inc).

Could somebody explain what this all means?
Any advise about what to do?

Hi and thanks for the helpfull forum. I need some help re the website www.topplaces.co.za. (I have been assigned to look after the companies websites. Im not familiar with Drupal, but have a keen interest, coming from 3 years of Joomla developing.

Anyway, as you will see this is a very advanced site and I have someone working with me on this site. This site makes the company money by adding "establishments". Ok so I figured the site uses Ubercart.

Hi.
I just upgraded a site from 6 (latest) to 7 (latest) folloing the upgrade.php steps.
Only thing I didn't follow was set the site offline as it's a test site on a private server.
