Migrating to Unified communications exchange 2007

we are currently using unity 5.0 and it is in its own active directory domain and forest as well as the exchange 2003..we want to move to exchange 2007 unified communications and this is in a different domain/forest as well...what would be the proper steps to migrate over in a situation like this from untiy 5.0 in one seperate forest than exchange 2007 thats in another forest?

Re: Migrating to Unified communications exchange 2007


This is really more of an MS question.

But I take it you are using Unity VM only for exchange? If it is a separate AD then the only info in that AD is used for Unity so you dont really need to keep any of it.

If it's in a separate AD then why not just configure your exchange 2007 for UM in parallel.

In CallManager you can configure a separate voicemail profile for Exch UM and assign it to certain users.

Have you piloted this yet? There are some limitations with UM for Exch 2007.

You can export subscriber information from SQL database on unity, and use it with powershell script for exch 2007 to actually get the users across.

I'd say when people move, they are going to have to re-record greetings, and lose their old voicemail etc.
