Granted, I wouldn’t do a cp or scp unless in a maintenance window. If you are just running a hypervisor, much like most of our install base uses, there are no tools to do this without spending money, at least that I’m aware of.

Also, in my experience, cp ans scp are very slow compared to tool meant for moving VMs around (E.g., Veeam Backup/Copy and VMware OVATool). Anyway, I'm not saying that I know best, I'm just saying, that's what the vendor says.

>> For a major upgrade it seems pretty reasonable to me. I'd consider doing it just for testing even if I upgraded the production servers directly rather than shut them down and start up the upgraded ones. And if I was going to do a parallel upgrade, I'd probably upgrade once to test, then copy the production servers across again and do it for real. One thought that comes to mind is how quickly you can copy back the VMs from AWS to your production environment.

This part of the discussion was focused on how you could use VWC on AWS to accomplish this if you didn’t have resources. The CSR would, if it works, allow you to connect devices on prem to the offline servers to do a more complete testing. But it’s not entirely necessary.

>> It’s all what your more comfortable with, I guess. I’d rather double the amount of prep time to complete the upgrades offline in order to reduce the downtime to the production service. Especially when both CUCM and UCCX need to be upgraded simultaneously due to version compatibility.

>> I will say one thing, if you have the opportunity to duplicate the environment in an off-line network and perform the upgrades there, then your migration will basically be downtime involved with shutting down old servers and turning up new servers. This is not trivial, by any stretch of the imagination. However, once you put some thought into it, I think you’ll find this method extremely valuable.
