Hello,
I need to upgrade a customer from FPBX 12.0.76.6 to the latest FPBX 15 version. However, I cannot upgrade the production server as we have attempted twice and have been met with issues each time. As such, is there a way to perform the upgrade on a lab environment server, while leaving the production server untouched and function (i.e. not de-activating deployment ID)? I know that Digium allow multiple coterminous registrations for this purpose.
Any help is greatly appreciated!
Jon
