Update Callmanager 3.3(4) to 4.2(3)

[rgassmann]

Hello

Thank you all for your help with the symantec issue.
Has anybody experience on how to update a Callmanager 3.3(4) to 4.2(3).
We have to update our system next year.
We also have IPCC 6.0 and CRA 3.1(2)SR3 running.

Especially the function of the new HuntGroup Feature is an issue for us.
Has anybody tried to CallForward or PickUp a HuntGroup? We currently have a
third Party application (Monday Coffee) installed to handle the HuntGroup
functions. With this tool the call is presented on the line of the phone.
So if the phone is forwarded to another user all HuntGroup Calls are also
forwarded to this user. Is this solution still possible with CCM 4.2(3)? We
currently use different callforward destinations such as openinghours / all
agents ar busy / and so on.

Thanks for your inputs

Don't know about upgrading from 3.1 but a few months ago we upgraded from 4.0 - 4.2(1). This wasn't without problems, some out of our control, and we had to rollback. We then built a test Publisher and upgraded that and once we were happy upgraded the live version.

We had the express version of IPCC running on the Publisher I think it was a freebie (5 licences) from the original install which only one dept uses - Be warned! We could not update this (which a Cisco engineer at their head office agreed with). We had to install it again after the Call Manager upgrade and we had to manually copy all the set up of the IPCC as well and set up again on the new installed IPCC. New Agent, Supervisor and Administrator plugins needed to be installed on all the clients to worlk with it.
Let me tell you it was a bit of a nightmare getting the IPCC all working again especially when a couple of entries of the config was missed! So I would strongly suggest you carry out a test upgrade!

We don't use any 3rd party software for call handling, however the big feature of 4.2 for us is 1. logging in and out of hunt group and 2. actually being able to pick up a group call rather than wait for it to arrive at your phone.
Bear in mind that this 2nd feature needs to be enabled by entering a Parameter Value code in Enterprise Parameters
