I am trying to update my install of WSS 3.0 (installed on Server 2008 R2 x64) to the newest version I can find, I am currently on 12.0.6425.1000. I went and downloaded SP3, however when I run try to install it says:, however it does not specify what version I need to be on to update directly to SP3.
I have been looking at this page that lists all the available updates, but when I try the oldest, and most recent hotfixes for SP2 it says package installation failed.
Interestingly enough my first though was go from WSS to Sharepoint Foundation, However that is also problematic as the pre-migration checklist fails with(full text here):
Microsoft.SharePoint.Administration.Health.InvalidDatabaseSchema [InvalidDatabaseSchema] [DEBUG] [4/30/2013 9:15:50 AM]: Checking schemas in content database WSS_Content... [SPUtility] [DEBUG] [4/30/2013 9:15:52 AM]: File C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\Template\sql\store.sql, Time out = 600 sec [DatabaseSchema] [ERROR] [4/30/2013 9:16:11 AM]: [WSS_Content].[SearchAllTables] EXTRA String [DatabaseSchema] [ERROR] [4/30/2013 9:16:11 AM]: [WSS_Content] NON EQUAL Property SProcs [InvalidDatabaseSchema] [DEBUG] [4/30/2013 9:16:11 AM]: Checking schemas in content database SharePoint_AdminContent_dc35930d-0163-48fc-8c32-89028dea0293...

Status = Failed [SPObjectProcessor] [DEBUG] [4/30/2013 9:16:17 AM]: The rule failed.
So my question is how do I get update from where I am to something newer?
EDIT: I am making some progress on the service pack front but it is very tedious. I download the next oldest hotfix install and then run the Sharepoint products and technologies config wizard. Is that necessary after each hotfix, or can I just install all of them then run the wizard?
