I'm going to be upgrading my CCM 4.1 system to 6.1 soonâ¦
I also want to replace the hardware on my Publisher only.
So I have installed 6.1 on the New publisher as a new node to play around, I have my license file installed.
My plan is to Run the Final DMA export a week before the actual move then reload the new CCM pub as an upgradeâ¦
I have three other subs in the cluster...
My question is as follows, when loading the CCM Pub should I load the box with the same ip address and host name
Or use a different IP and hostnameâ¦
The pros on changing the name & IP, is that I can load the CCM pub during the weekday with the upgraded data,
I can make sure everything is 100% working before I down the production pub & then the 4.1 subs.
Two of the pubs are in a city 60 Miles to the north and I will need to drive to them to load them up.
They are not in production so I can load these wheneverâ¦
The cons to changing the ip address is that I will need to update my voice gateways to point to the new CCM PUB for its configâ¦
If I use the same IP address and hostname, I may still choose to load the DMA data a week ahead and just not put the box on the network until the moveâ¦
One last gotchaâ¦ Im running DHCP on the PUB for my phonesâ¦ Now I know CCM will not move the DHCP at allâ¦
Or do I take a bit of a risk and do a DMA export the night before the upgrade and then just upgrade the new PUB with the same IP & Hostname as if it were a "normal" upgrade?
Any one have any suggestions on this?
