I need to upgrade Unity 4.0.5 without failover to Unity 8, and we are replacing the server as well.

What would be the most efficient upgrade path for this?

The most efficient path is to use COBRAS.  I have a number of posts explaining the overall process.  At the highest-level, this allows you to build out the new Unity 8x environment, get it integrated with AD/Exchange, and then build out configurations that don't migrate over (there are a few which are highlighted in the COBRAS help).  From there, you migrate data over from the 4x system.  There may or may not be a few steps along the way but they are outlined in numerous posts I've contributed to regarding COBRAS and also in the COBRAS Help which is located at www.ciscounitytools.com.
