Check Point gateway cluster upgrade procedure in Azure.
I was told, in Azure you will bring up a brand new Check Point Cloud Guard cluster with the latest build and version and you will then shut down the old cluster, remove the NIC and attach it to the new Cluster you brought up
I am trying to do this setup in my lab, however I cannot remove all the interface attached to the cluster, I am getting following error
ErrorMessage: Virtual machine XXXXXClusterA1 must have at least one network interface, and its not allowing me to remove the NIC
The Cluster VM's are shut down and deallocated and I am able to remove one interface (eth1) from the cluster, however eth0 I couldn't remove
Please let me know if there are any better way to upgrade the cloud guard cluster with minimal downtime
