We have several SharePoint 2007 farms with several site collections in certain databases. The desire is to be able to migrate these 2007 site collections to our new 2010 farm envirionment. The best way to do this is the Database attach method.
However when i do the database attach, certain functions of the sites fail. This varies per site collection from menu structure to the site not working at all.
The cause of this is because the 2007 envirionment contains several web parts and features that the 2010 envirionment does not. Also the look and feel has drasticaly been changed.
To adres this problem we decided to create a new and clean SharePoint 2007 envirionment and first attach the "dirty" 2007 database there. After that we changed the look and feel and all web parts and features seemed to be gone.
However when i run Test-SPcontentDB on this "Clean" database, it gives me the same errors as te dirty one! The end result is also the same. So my question is, is there a way to remove these web parts etc. from this site collection? So to do some sort of clean up on the database.
I cannot remove the web parts and features from the original server and DB because it is a production server.
