cphaprob state: 'during cluster upgrade'

[Reaper]

I have several clusters from R55 to R62 and have not had that problem so far:

# cphaprob state

Cluster Mode:   Sync only (IPSO cluster))

Number     Unique Address  Firewall State (*)

1 (local)  gateway1.ip  down (during cluster upgrade)
2          gateway2.ip  active

(*) In IP Clustering/VRRP FW-1 also monitors the cluster status

This happened to cluster after I had upgraded it from R55 to R62. The way I do upgrade is that first I remove all R55 packages and then install R62 packages.

The problem is that now I can't enable FW monitoring in IPSO cluster. if I do, the cluster dissolves and all stops working. So far the VPN works, but i guess the cluster cannot switch automatically because of disabled monitoring.

The question is, how to get the cluster into active-active state again? I have tried restarting, deleting and creating IPSO cluster, reloading policys and even reinstalling CP R62 packages. Nothing seems to work.

Only reference that I found from the web is:

I read the CheckPoint_NGX_UpgradeGuide.pdf and it was not helpful, my current problem is not mentioned anywhere either.
