I am trying to upgrade SharePoint 2007 web application to SharePoint 2010, I am using attach and de-attach method.
Below is the content database information:
- Database Size: 66 GB
- Site Collections: 1 Site Collection
I am facing a very strange problem during migration, after running the below command
stsadm.exe -o addcontentdb -url [http://sitename] -databasename [databasename] -databaseserver [databaseserver]
After running for a long time, it got stuck on X percent (not specific number) and it shows “Upgrade In Progress” in the central administration.
I though may be it needs sometime to finish the current action. But after waiting more than 16 hours, the percentage didn't change, the central administration is still showing In Progress and no errors are there in the log. I tried many times to upgrade the database but same problem happens every time.
