Migrate Exchange 2010 to new hardware

I need to move an Exchange 2010 build off of some legacy hardware. I'm hoping to do a VM connected to a new SAN. Are there any guides on moving from Exchange 2010 to Exchange 2010? I don't want downtime. If possible, I might look at p2v conversions. We also don't have System Center so I would have to use the Xen p2v which makes me a bit uncomfortable for a critical application.

I used it and migrated nearly 80 servers on 40+ sites...As far as downtime is concerned, mailbox move from Exchange 2003 to 2010 is offline, so users who's mailbox are in move process will be offline rest will be working.

P2V is not required here, just setup new 2010 server in same Exchange org and follow the articles given above.

This is for 2003 > 2010. Will this be applicable for 2010 > 2010?

If you want no downtime then P2V isn't an option.
A regular migration is completely risk free and involves minutes of downtime per user. As such if you schedule it correctly then it can be done with zero downtime for users. It is the only option I would consider.

Ok. So is there a guide for 2010 to 2010?

You don't really need one.
Install Exchange, replicate public folders, move OAB, move mailboxes. When you run add/remove programs it will tell you if anything has been missed.

The biggest headache people have is moving the clients, because unless you have an RPC CAS Array you will not get the clients to move to the new server. That will mean touching every client to get them to update.

There is no migration guide within same exchange org, As Simon said you need to setup new Exchange server and move over the mailboxes etc. to new server.

My suggestion would be keep both servers and load balance accordingly.

I think I'll look at doing a CAS array. In the past, I had a login script that pushed a PRF file to switch servers in Outlook. I'm curious as to if that will still work. I'll have to test.

In 2010 that is not required as you have auto discover feature. I installed several servers and moved mailboxes and never touched a single user for any change.

I wish I could ask a few more questions. I've moved a mailbox and Outlook automatically pointed to the new server. I'm trying to understand whether or not I need the CAS Array. I'm having a lot of trouble trying to get answers.

As far I am concerned, you need a CAS Array.
Every implementation I do gets a CAS Array whether they want one or not.

Fair enough. So do I only point new databases on new server to it since the old one is going away?

Set the CAS Array on all databases in the AD site. Then you can repair the profile on all mailboxes before or after moving them - it doesn't matter.
