Which upgrade path must be used?

A technician is preparing for an upgrade from Workforce Optimization (WFO) Vll to Avaya Workforce Engagement R20.X.

Which upgrade path must be used?
A . Side-by side or hardware reuse migration to R20.x
B . Two step upgrade process, to V15.1 first, then to R20.x
C . Side-by side upgrade to R20.x in Windows 2016
D . In-place upgrade to R20.x in Windows 2012 R2 (grey kit)

Answer: B

Explanation:

The upgrade path from Workforce Optimization (WFO) Vll to Avaya Workforce Engagement R20.X is a two step upgrade process, to V15.1 first, then to R20.X. This is because WFO Vll is not compatible with Windows Server 2016, which is required for R20.X. Therefore, the first step is to upgrade WFO Vll to V15.1 on Windows Server 2012 R2, and then the second step is to upgrade V15.1 to R20.X on Windows Server 2016. This upgrade path applies to both side-by-side and hardware reuse migration scenarios. The other options are not valid upgrade paths for WFO Vll to R20.X.
