Preamble
There are a lot of different of different scenarios, issues and methodologies realated to upgrade from Sharepoint 2003 to 2007 (WSS or SPS).
Generally:
- Check the service pack of SPS 2003 to match the prerequisites;
- Backup the existing Sharepoint databases
- Launch prescan /all on your server to be upgraded to check that Sharepoint is ready to be upgraded. You can find this utility on an 2007 installation under <%root%>\program files\common files\Microsoft Shared\web service extenstions\12\bin directory and copy it to the 2003 installation (allowing you to execute it);
- Manually fix all the errors found from Prescan;
- Proceed with the upgrade (accordingly to Microsoft brest practice);
Usually every time you'll find different errors depending to the Sharepoint topology and configuration.
This morning, I've found the following errors migrating WSS 2.0 to WSS 3.0:
- Launching prescan /all the log files was:

Usually the first thing you've to do with this kind of problem is trying to fix them with:
STSADM -o databaserepair -url http://customer-server -databasename customer-content-database
With this command all the orphaned entities in Sharepoint content database are found and fixed (removed).
The problem is that SOMETIMES stsadm is unable to find orphans so that prescan doesn't complete succesfully and you cannot upgrade...
To fix that you can MANUALLY force orphans in the content database directly working with Sharepoint database tables.
The idea is getting the entities id from the prescan log file (in our example the site with id=ef24fe63-efdf-42b7-b431-a9ae04abc24a and the list with id=b5f896c9-8f1c-40d2-9282-1154ccbaf6cb).
For force the orphans connect to Sharepoint content database and executes the above sql commands:
use customer-content-database
delete lists where tp_id='b5f896c9-8f1c-40d2-9282-1154ccbaf6cb'
delete sites where Id='ef24fe63-efdf-42b7-b431-a9ae04abc24a'
Now go back to the command line shell and execute:
STSADM -o databaserepair -url http://localhost -databasename customer-content-database -deletecorruption
So that you will the orphans removed.
Now you can launch prescan /all and it should run succesfully.
Keep in mind that you've to manually fix each error discovered by prescan. Each time you've to find a workaround! This SQL code must be adapted to you scenario and you should have to deal with others Sharepoint tables!
