  • Hi,

    We are getting error while importing the files from SharePoint 2007 one server to SharePoint 2007 Other Server.

    Have anybody faced this kind of error while importing of the files. The error is as below-

    FatalError: There can only be one instance of this list type in a web.An instance already exists.

  • Means exactly what it says; content already exists that you're trying to import.  Each list / library within SharePoint has something called a GUID, a unique identifier that's attached purely to that list. 

    Have you activated publishing, or do you have any custom lists created?  These are the common offenders.
