So we have a 5100 , actually we have two 5100s and we are planning to use them in a cluster (both have just been freshly configured with nothing but ip information so far), below are the details for one of these 5100s-
show asset system
Model: Check Point 5100
Serial Number: xxxxxxxxxx
CPU Model: Intel(R) Celeron(R) CPU G1820
CPU Frequency: 2195.026
Number of Cores: 2
CPU Hyperthreading: Disabled
Now the problem is both of these firewalls are running Gaia R80.30 out of the box but our management servers (we have 2 servers primary and secondary) are running R80.20, now is it possible to downgrade these firewalls to R80.20? i know that right now we should all be on R80.30 at least but we are actually planning to upgrade all of our firewalls along with servers to R80.40 next year which will be a separate project. Following link is what i found which makes me think that the firewalls do support R80.20-
In the above link "5100" is mentioned as one of the supported models, so i guess they do support R80.20?
Also if they do support R80.20 what is the method i should use to downgrade? I do know about the fresh install using the isomorphic tool via usb device, is this the recommended method? And possibly the only method? And the image included in that link above is an iso image by the way.
Thanks and Regards.
