SPObject.Resolve()

I had a task to migrate the content database of a web application in SharePoint 2010 to SharePoint 2013. I performed the database-attach method (the only possible with SharePoint 2013 migration) and everything seemed to be working. The problem came when I navigated in the document libraries. There were a lot of missing files. At first, it looked scary but the reason was logical:     - I migrate the web application to a new farm with different Active Directory     - The missing files didn’t have published version so they were not missing but hidden     - Even I was logged with the System Account the security trimming hide these files The way to make the files visible is to publish them. Just navigate to   Library Settings -> Manage files which have no checked in version  . From here you can take the control over the documents and to publish them: Looks simple but it took me time to identified the issue.
