[cisco-voip] CM 3.3.4 or 4.0

[Voll, Scott]

Here is where I'm coming from.  I have an ICS 7750 with CM 3.3.4 and
Unity 4.0.2 and IPCC Express 3.1.2 (running on a 7825).

We have just purchased two 7835's and another 7825; publisher 7835,
subscriber 7825, Unity 7835, IPCC Express still on a 7825.  

We will be migrating to CM4.1 and IPCC 4.5 as soon as they are out for
added features.  But I need to move over to the server platforms now.
Should I stay with CM 3.3.4, remove HDs and install CM 4.1 when the time
comes, or install CM 4.0 and upgrade to 4.1, or install CM 4.0 and
remove the HDs and install 4.1.

If my users are use to CM 3.3.4 will I have issues moving to 4.0?  Does
anyone have a link to the differences between CM 4.0 and 3.3?

Which would everyone suggest?
