We are going to upgrade CCM 4.13 to 6.12 with new servers.
And we are trying to install at off-network now. The first node (publisher) is installed successfully and import DMA, and upload license without any problem.
However, when I tried to install the second node, it said I can't reach first node. Now, I am thinking that I dont have DNS server at the off-network, is that thats the reason??
