[cisco-voip] Not supported I'm sure..... but what do you think?

[Tommy Schlotterer]

I do a similar, but supported process. I take DRS backups and then restore on servers in a sandbox VLAN. Works well. Make sure you check your phone firmware and upgrade to the current version before the cutover or all your phones will have to upgrade on cutover.

Also make sure you don’t change Hostname/Ip addresses in the sandbox as that will cause your ITL to regenerate and cause issues with phone configuration changes after cutover.

Thanks

So my co-worker and I are thinking about upgrades.  we are currently on 10.5 train and thinking about the 11.5 train.

What would be your thoughts about taking a clone of every VM.  CM, UC, UCCx, CER, PLM,

placing it on another vlan with the same IP's.  NAT it as it goes onto your network so it has access to NTP, DNS, AD, etc.

do your upgrade on the clones.

Then in VM ware shut down the originals,and change the Vlan (on the clones)  back to the production vlan for your voice cluster.

it would be like a telco slash cut.  10 minute outage as you move from one version to the other.

Thoughts?

Scott
