Hi,
I have a pair of 5800 gateway appliance running R81.20 in HA mode. These devices go end of hardware support today (30 Sep 25) and I have a pair of new 9400 appliances due to be delivered in the next few days.
I anticipated that the new devices will come with R82 and so I have pre-upgraded our management from R81.20 to R82 already.
I know that R82 and R81.20 appliances cannot sit in the same cluster and obviously cannot have the same HA or IP addresses as the existing devices, but what I cannot find is any documentation showing the best way to replace them.
This is how I am planning to approach this:
1. Build / Install the R82 gateways with a new management address (and adding them to firewall rules).
2. Configure interfaces and IP addresses the same as R81.20 counterparts, leaving them disabled.
3. Add routing tables and Proxy ARP the same as R81.20 counterparts.
4. Failover 81.20 to the Secondary
5. Shut down the R81.20 Primary
6. Reset SIC on the Primary host in the cluster object
7. Enable interfaces on R82 Primary.
8. Upgrade cluster object to R82 and rest/initialise SIC for Primary host.
9. Push policy to individual gateways (Should work on R82 and Fail on R81.20)
10. Failover to R82 Primary
11. Repeat steps 5, 6, 7 for Secondary appliance
12. Push policy to gateways
I don't know what will happen in step 7-9 when I bring the R82 primary online. Will there be two devices trying to become ACTIVE?
In step 10 will I have to shut down R81.20 Secondary to get the failover to work properly?
I would like to hear your comments and advice on this.
(Thanks in advance)
