I currently have Kixtart 3.63 on all of my Domain Conttrollers (12 in total throughout the network).

I do run the kix as a service on each.

What is the best way to upgrade to 4.11 on each.

Do I just stop the service and delete the old files? or do I have to uninstall in a special way?

Please provide any things I should ensure to do and be careful of.

Thank you
