The 'Use relative path for file within database folder' option on the Insert Hyperlink dialog applies only to filenames like D:\Temp\test.urd and not UR inter-DB links like ur://D:/Temp/test.urd?item=1006,1000.
Inter-DB URLs are currently stored with absolute paths and must exist at the path in the URL. You could create a symbolic link to point from the old .urd path to the new location.
