A client of mine is about to migrate is old SCADA system to Ignition and asked me a question I could not answer about Redundancy.
The idea is to have Ignition Gateway running within a virtual machine (Let us call is “Master”). The virtual machine is daily snapshot on another computer (Let us call it “Backup”).
Whenever the “Master” fails, my client would like to manually activate the Gateway by launching the snapshot on the “Backup”.
As far as I know, all should go fine in this operation but there is a point about the licence. Indeed, it has been activated in the Master Virtual machine. Will it still be activated in the Backup ? (The virtual machine files are the same, only the computer changes)
Thank you for your enlightenment.
