After patching our Test environment of SharePoint 2010 to Service Pack 2, Our project leader told me there is a website that need to go to production. Production is still in SP1. He planned with me to give the patching priority and told nothing about the sites.
The sites have their own content databases. The problem is that i'm not sure now if it is possible to move the sites to production. I hope you can give me some insight in this. Normally we do backup -> Restore -> attach.
