Hello
I have a customer who is using 2 ZD1200s in redundancy.
Recently, the customer asked me to upgrade the firmware of the ZD1200. The current firmware version is 10.4.1.0.214.
Is there a guide document that roughly explains how long it will take or the procedure to upgrade the firmware of a redundant ZD1200 to a higher version?
I need information on roughly how long it will take to upgrade, what to watch out for when upgrading firmware, etc.
Thank you
