Hello @George_Thompson ,
Thank you for your answer.
Let me explain a little more in case you misunderstood.
I mean that, can I use tool itself on older environment. I will copy webgisdr folder from version11 and put in another machine version 10.9.1 installed. And take backup from 10.9.1 and restore it to 10.9.1.
Again the answer might be No but I wanted to make sure I spelled it right.
Thanks,
Suleyman.
