We currently have exchange 2003/SP2 standard about 200 mailboxes VM “ESX4.0” we use OWA, mobile sync and outlook anywhere we also have a BES for blackberries we currently use double take software in case of a failure. I’m looking to upgrade to 2010 I’m also looking at exchange 2010 HA if I have one exchange 2010 physical can I have the 2nd one VM? Is there is any helpful video for this procedure?
Thanks

Please note that exchange 2010 is compatible with BES 5.0. hence you might be looking at upgrading BES as well.

interms of using Exchange 2010 HA, you can use DAG but to avoid single point of failure, you are looking at 1 physical exchange 2010 and another VM exchange 2010 on a seperate physical box.

in regards to upgrading 2003 to 2010, can see the below including MS virtual labs that you can do

You can have a mixture of physical and virtual if you desire. The key difference between the Exchange 2003 clustering and Exchange 2010 High Availability is that Exchange 2010 doesn't require shared storage. Take a look at this video to get an idea:

Exchange 2010 doesn't support utilising VMWare HA, so I would disable VMotion for the 2010 servers. It's not required anyway as you'll be replicating data between two servers (one physical/one virtual)

from my understanding the price difference between having two windows enterprise edition servers plus two exchange server licenses well exceeds the cost of double take

if you still want to consider using exchange 2010 ha, it is difficult to truly accomplish with only two servers (whether they are physical or virtual doesn't matter)
