migrating exchange 2003 to exchange 2010 running on Windows Server 2012 (standard).

We have migrated our DC from our Windows 2003 server to our new windows 2012 (standard) server. We still have the old 2003 server configured as a DC also. We would like to decommision our old 2003 server on completion, so when would you recommend disabling the DC on the old server? After migration of exchange or before?

We have exchange 2003 still running on our old 2003 server, and would like to :-

1). Install Exchange 2010 on our new 2012 server
2). Migrate our exchange server from the old 2003 to the new 2010 version on our new 2012 server.

Will mail services be affected during migration, and if so, at what point? Ideally we would not like any lengthy outages, as this is a busy live site.

Can anyone recommend any documents, videos (youtube) etc which details this process, as I would like to be as familiar with this process as possible before I start.

We do have access to the Trainsignal library, but can find nothing which relates to the exchange migration.

Any advice would be welcome.

Many thanks.

We have been informed that Server 2012 may still presents some problems with Exchange 2013, so decided to hold off on that till we were certain all was well, with appropriate SP's available etc. I was also under the impression that it was a 2 step process anyway from 2003 to 2010 then to 2013??

I have looked at some of the guides which indicate that we install Exchange 2010 on the new 2012 server.

Having not done it yet, I am just a little confused as to what to expect. Will the new exchange 2010 installation be aware of the 2003 exchange sever, and will it configure the hub transport etc automatically, or is this something we do during the Exchange 2010 installation. If this is the case I was unsure as to which exchange sever would provide the hub transport, ie the actual link with the outside world. If not, at what stage do we start using the new sever to send / receive mail??

We currently have port forawrding pointing at our 2003 server. Is it just a case of changing the destination to the local IP address of the new Exchange server??

Many thanks.
