Changing SBS 2008 to Server 2008 R2

I want to move my Exchange 2007 on SBS 2008 in house to Office 365 online.
Then  I want to put Server 2008 R2 on the system where SBS 2008 is currently on.

I have backups of SBS 2008 so I can restore if needed.

What steps do I need to take to do this correctly. I do use active directory and have dhcp and dns on the SBS 2008.  

Thanks

I do have another server I could use to help in the transfer.  

I don't do this enough to remember the steps.  Install Server 2008 R2 on the second server and what would I need to do next. I have an idea but I don't want to do this twice.

Procedure would be a bit like a swing migration as described at http://www.sbsmigration.com/pages/96/
They actually have a kit for this scenario.

Next you install the AD DS role to make it a DC.  This will also install the DNS role.  The SBS should have all of its DNS zones set to AD-integrated, so they should replicate along with all the AD info.  Depending on how long it will take from the time the SBS hardware is wiped and a new OS is put on, you may want to add the DHCP role to the temp server, or even if you can keep this temp server and make it a permanent second DC.  http://technet.microsoft.com/en-us/library/dd379535(WS.10).aspx
Also depending on this time, you want to modify the DHCP options to specify this machine as a DNS server, and/or modify static properties so other machines can find it.
Disconnect the SBS from the network.
Seize all the FSMO roles on the 2nd server.  Perform a metadata cleanup of the old server.
On the original hardware, after bringing up a new OS instance with same IP as old, pretty much perform the same steps all over again as you did with the 2nd server, which is add AD DS, DNS, allow for replication, transfer FSMO roles.  On whatever machine will have the PDCe FSMO role, set it up to synchronize to an external time source.
Transfer/install DHCP as needed.

Ok, I have added another DC with DNS and have tested it.

When I am done migrating to Office 365 do I then remove the AD function from the SBS 2008 and install DHCP on the new DC ?  

I want to put another 2008 R2 on the existing SBS 2008 drive or at least that is part of my existing plan unless something else makes more sense.

Thanks

Thanks, One final followup question. You have been very helpful.  

We are not a big organization we only have nine users.

I have an SBS 2008 server with data on one raid drive and the os on a separate raid drive.  I want to remove all the shares on my data drive then load Server 2008 R2 on as the new OS, setup AD with users then share the data drive again.  

I have just been having too many issues with SBS 2008 and once I move to Office 365 I want to abandon SBS 2008.

Do you see any problems with this plan?

There shouldn't be any problem with this.

I'm a little surprised that you've had many issues with SBS.  My experience is that it works very well.  Of course, experiences differ.  Good luck.
