[cisco-voip] IPCC Express upgrades 4.x to 5.x 6.x or 7.x

[Micah Bennett]

Hello all

Just doing a little research on the upgrade options for our system.

I have the compatibility matrix for both call manager and ipcc express.

The call manager matrix shows the support to and from upgrade paths
using the DMA tool or direct upgrade.
I know that it is mostly a new install because of moving form
windows/sql to linux/Informix.  The DMA tool just helps bring over your
data so its not a 100% scratch rebuild.

What about the IPCC versions.  The matrix does not seem to show the same
to and from data.

It looks like the IPCC express systems continue to use Windows for their
OS.  Is this correct?

Does anyone have a link to any document that shows the supported and
tested upgrades from one IPCX version to another?

For the group members that have done a full system upgrade, did you
upgrade a live system or purchase new hardware to put the upgrade on.  I
would assume that using new hardware is the best way to have the least
impact on a working system.  I imagine that a full upgrade of all
systems is going to take a few days, and not a few hours in the
maintenance window.  We have to be especially careful because we are a
24x7x365 call center.

Thanks
