In this post, we will discuss how to solve the lookup column issue in SharePoint 2013. Recently we were migrating from MOSS 2007 to SharePoint 2013 using database upgrade approach. So we first move from MOSS 2007 to SharePoint 2010 and then from SharePoint 2010 to SharePoint 2013.

After the migration in one site, we see that one lookup column is appearing as blank in one of the list forms when user trying to add one item to that particular list.
We verified the list and found out that the list is actually created by using an existing list template. And when we verified the list template (manifest.xml) file we saw that the Lookup list id has a different id in the SharePoint 2013 site. So it was not pulling the list items.
We modified the updated manifest.xml file in the list template with the updated list id and then uploaded this newly modified template and it works fine.
To modify the list template file, first, download the list template file which will be an extension of .stp. Then rename the file to .cab.
Then use tool like 7-zip to unzip it and once the file is unzipped you will see manifest.xml file. Open the file in the notepad and then Save the file.
Then use makecab.exe to convert the file to cab file like below:
makecab.exe F:\Users\Administrator\Desktop\MyTestListTemplate\manifest.xml F:\Users\Administrator\Desktop\MyTestListTemplate.cab
The above command will make the .cab file. Then rename the file to .stp from .cab.
Finally, upload the .stp file to the list template gallery.
Hope this will be helpful.
