[cisco-voip] Consolidate two separate UCCX cluster and migrate to 9.x

[Ashwani R]

Team,

I have a customer who has two separate UCCX HA cluster with their
respective CUCM cluster (merging two companies).  They would like to merge
both CUCM and UCCX cluster to one cluster and upgrade them to 9.x.  They
are running CUCM version *7.1.3.10000-11* and UCCX cluster running *7.0(2)
Build254*.  What is the best way to do this? Can they keep both historical
data from UCCX and move them to 9.x ?  I know this is not possible but just
want to see if anyone has done it before.  We have already built new 9.x
CUCM and UCCX cluster with new set of IP addresses with blank
configurations. Any help will be appreciated.

Thanks,

Ashwani
