Looking for advice, opinions, experience on the necessity to upgrade to the latest Call Manager release.
The current setup:
UCM v6.1.2.1000-13
1 Publisher, 2 Subscribers
All are Cisco 7825H3's (HP), Xeon 3050@2.13GHz, 2GB memory, 160GB Sata HDD's.
O/S version 2.4.21-47.ELsmp
1318 phones - 79xx models. skinny
313 ATA's (mostly 186's, some 188's)
30+ Gateways (MGCP)
H.323 Gateway H.225 2
Voice Mail Port SCCP 63
Unity v 7.0.2 with failover
2 virtual Windows Server 2003 SP2
VMWare v3.5
Voice Gateway 3745 v12.4.(15) T11 / H.323
WAN/LAN consists of Metro-E's, T1, DSL's.
Remote routers are usually Cisco 2851,2821, 2801, 1760 and 8xx models.
Switches Cisco 35xx, 29xx, 3002 VPN hardware clients.
Cisco 3745 v12.3(14)T7
Cisco C6509-E v12.2.33 SXH3
Primary DNS Server 2008, secondary DNS Server 2003.
The current UCM cluster has been in production for almost 3 years.
The cluster has operated without major problems during this period. The only hardware incident was a memory module went bad.
The majority of the IP phones have been purchased and deployed.
What are the advantages to moving to UCM V8.x on a virtual server?
I would envision installing/building the new version on a vm server and then importing the existing data.
Can UCM 8 run on VMware 3.5, or do I have to stick with a Cisco product?
Will the affected routers and switches need the IOS to be upgraded to a recent version?
Any other thoughts, experiences you can provide.
Thanks.
