We are in a process to upgrade our 3 cluster from R77.30 to R80.20. all are currently managed by windows R77.30 management server. Model numbers are checkpoint - 4400 [9 Standard rules and 4 NAT rules], 4600 [36 standard rules and 21 NAT rules] and 4800 [400 standard Rules and 222 NAT Rules] with 4 GB RAM on each box. One is in VRRP and one is in cluster XL cluster. RAM upgrade is not an option here as in 3 years devices are end of support too.
1. I have read certain article where it says 4 GB RAM is fine but recommendation is 8 GB RAM. We do not use IPS, Threat detection etc features. so is this memory is sufficient for R80.20 ?
2. in practical approach where CP customer upgrade is already done to R80.20 in 4k devices with 4 GB RAM - Did there are any performance issue. Do CP receive such calls post upgrade ?
3. If can't go to R80.20 - can we go to R80.10 with above specification ?
4. Tentative date of R80.10 to be end of support ? I know in each 2 years lower CP software is going end of life so just wandering ?
