I have one question about clustering , I wanted to perform the hardware upgrade to the firewalls, we have 2 locations total 4 firewalls. There is a fail over configured between these locations.
Say for example in location1 am going to do hardware upgrade with IBM or HP machine but in location2 am performing the upgrade with different hardware but looks like same make with different model, but for sure am going to use different one. My question is when the fail over between the location happens , will that cause any issues with the above scenario or fail over will be transparent to users. Software versions are going to be same.
I believe it will cause some issues. Please share your thoughts!
Thanks in advance.
