Hi Siva

To reach the latest version of CUCM starting from 3.3 you need different upgrade steps.

The very first is to upgrade 3.3 to 4.2 and than to 7.1 via DMA.

Here is a doc where you can find different upgrade options.

Hi Siva,

your tasks for upgrades would be  from version 3 ---> 4 . then , from 4----> 7. I suppose same hardware u are going to use from version 3 to 7 .

What is the hardware u are using for upgrade from 3 to 7?

U are correct, VM is supported from 8.

Aman,

You are exactly rite,from 4 to 7 i need to go for a different hardware am i rite,as u said from 7--10 i can upgrade through PCD,,,So in this case i don't want  upgrade to 8 to support VM?

Siva,

there is no point upgrading to 8 . From 7 , u can go to version using PCD.

Hi ,

From CCM 4 , u can upgrade to version 7.1(3). 

U need to download Data Migration Assistant Tool and run on Call Manager 4.

you can refer notes of DMA and download DMA tool

I can find DMA 7.1(5) also .You can try downloading same and upgrade to CUCM 7.1.(5).From CUCM 7.1(5), use PCD to go version 10.

Aman,

In this case i should deploy PCD in VM environment,then i can upgrade to latest version.,but as i seen in compatiblity matrix VM supports from the version 8.X.,this make me confused!
