I am trying to import data on fresh instance from old instance , But I am facing below Warning.
"File did not contain any valid data. Nothing was Imported"
Please suggest any solution.
What data you are trying to import? Check if the all the setup are same for the import and export definition groups.
Tell us how you are doing the import right now? For reference see, ttps://technet.microsoft.com/en-us/library/aa834325(v=ax.50).aspx
