Relink InfoPath Forms in SharePoint Online
After migrating InfoPath form from SharePoint 2010 to SharePoint online, I saw that form templates links were showing old SharePoint 2010 server URL. Now I have relinked it. To relink, Go to Library Settings Under “Permissions and Management” group, click on “Relink documents to this Library”. This will take you to the “Repair.aspx” view. Now go to “Files” Under Actions group, you will find “Relink” AND “Relink All” button. Just hit Relink All to link with current site.
