[cisco-voip] CUCM 6.1 upgrade

[Lemon]

Hi,

Currently running:
 CUCM 6.0.1.2000-3,
Unity Connection 2.0.1.2000-337
CUPS 6.0.1.1000-21 used as a SIP Proxy with a SIP Trunk to CCM
ARC Connect Server 4.1.0.400 (SR2)
ICM 7.2.2
CVP 4.0.2es9

and we are planning on upgrading to CUCM  6.1 shortly and was
wondering if we needed to upgrade anything else like TAPI drivers or
jtapi drivers? Anything else we should look out for?

Thnx
