we are currently running Exchange 2003 on win 2003 Srv
BES 4.1 on Win 2003 Srv.

we are planning on upgrading to exchange 2010 and BES 5.0.

do I need to upgrade BES first? can I still use win server 2003 for the BES server with the exchange connector from 2003?

I understand that I need win 2008 srv 64bit for exchange 2010 to work.

is there a step by step to accomplish this?

thanks

Id just do the exchang emigration http://www.petenetlive.com/KB/Article/0000234.htm then do a fresh install of BES - just make sure the version you install with 2010 is compatable
and you back up your BES Licences

I did something very silimar a couple months ago.  I went from SBS 2003 to Exchange 2010 on 2008 R2.

I used demazter's article on the Exchange portion:

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html

Between the above article at PeteLong's link above - that should get you through Exchange.

I also had Blackberry Professional 4.1 and was moving to Blackberry Enterprise Server Express 5.01 (now 5.02).  

Supposedly, it's not supported, but I did a fresh install off the BES Express and used the Blackberry transporter to move the users to the new installation.  I followed these instructions:

http://www.send4help.net/using-the-blackberry-enterprise-transporter-for-bes-migration-248


Though there are hundreds of pages with tutorials on the Blackberry Transporter.

Personally, I did Exchange first - moved the mailboxes over - and then did BES afterward.  I think that's the right way to do it.

And when I say it isn't supported - I mean the use of Blackberry Transporter.  In my case, it worked flawlessly.

I respectfully disagree.

I would move everyone to BES 5 first. Then do the mailbox moves. I would suggest using the enterprise transporter to move to BES 5 if you can. Moving to 2010 first can cause calendar issues for your users.

Basic overview:

1. Update BES 4.1 to BES 5.0 with SP1 and then MR1
2. Ensure all the required permissions and settings are in place for Exchange 2010
3. Move 1 user to Exchange 2010 and test all functions
4. When everything is working move all your users to the new server.

here's a full guide on how to do it:

Then follow the link at the bottom of the page to Migrate your BES 5 to Exchange 2010.


Also, make sure your permissions are correct on your new Exchange box.

I would have to agree with Kris, I am going through the same Exchange 2003 / 2010 Migration at this time,

I upgraded my BES to 5.0.1 long ago in preparation for this.

Here is a "Rapid Transition Guide" to Exchange 2010 from 2003

http://milindn.files.wordpress.com/2010/01/rapid-transition-guide-from-exchange-2003-to-exchange-2010.pdf

And a BB KB Article on how to setup the permissions for BES 5.0.1 and Exchange 2010

http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB22601

I would suggest running the Exchange 2010 Predeployment analyzer first, this is the first step to make sure all the pre-pre requisites are covered.  For example Exchange 2003 running in Native Mode, schema master at proper version etc. etc.

Because you have a BES, when you run the PreDeployment Analyser you will probably see a message about Permission inheritance being blocked on the Exchange 2003 server.  This needs to be removed in order for coexistance to work! (See link below)

You can even use ntbackup.

Back up the mail store and system state through there if you don't have a 3rd party software like Backup Exec / ArcServe.
