Thanks to the help of the community here I have successfully been able to use CSVimport to import my leasing Information into LDMS8.7!!
However, in my first template file I had a typo for "Last Update date" and had it as Last Update Data.. which then created an entry for every leased device which I would now like to try an remove from all of my devices.
Is there a tool/script that can go through and move all strings for Leasing Information - Last Update Data ??
