Hi mjcrank, I am glad you found my script useful.
Could you please tell me what modifications did you make to the script and to perform what exactly? It should work out of the box so no changes should be needed (except for the initial configuration of course). Also, which fields would you like to see updated that are not being updated already?
As for the PTR, if you want I can update the script to perform PTR update as well. Just let me know.
