Hello
I have an old 2010 environment, and I want to upgrade it to the new 2013 environment.
Besidse migrating/upgrading it I also want to add a portal to the Webapp which has to be the root site of the new 2013. So i created the WebApp, created a root Site collection in 2013.
Now i want the DB Y from 2010 migrated to my 2013 WebApp. Test-SPContentDatabase throws me an error aboute siteOrphan where the [/] already is in use by my new 2013 DB.
So what should I do to migrate the old DB into the new WebApp, retain the new root site as root, but not delete the content from the old “root” site…

I tried it now, it is a very slow process when my /root is 4 gigabyte. But so far this is my only solution.
