Default Setup new Exchange and BES while old server is active

Please Login to Remove!

Hi All,

Sorry if this question has been posed before but i could not find anything while searching.

Our situation is as follows:

The current environment is Exchange 2003 on Windows Server 2003. BES Version 4.1.4.12 on Windows Server 2003.

We are in the process of building a new Exchange 2010 SP1 server on Windows Server 2008 R2. We will also build a BES Express on a seperate Windows Server 2008 R2.

There will be no migration between Exchange servers or Blackberry servers, this is a totally fresh environment.

My question/dilemma is when i setup the new Blackberry server it will be using the same domain name as the current one. Will this disconnect users from the current Blackberry server? Or does Blackberry have records for each individual email address's server details?

I intend to migrate each user individually (there are only 15 users) so will add them one at a time to the new server.

I want to have the new environment as complete as possible before migrating any users so i would like to have BES connected, active and functioning.

Any feedback will be greatly appreciated.

Thanks

Greg

BES depends on Exchange. So if you have not created any mailboxes in Exchange 2010 yet, you will not be able to create any users on the new BES.

Thanks for the reply.

What I am trying to say is currently "example.com" resides on the 2003 environment. If I activate the new BES Express with new SRP etc. will this then become the BES for the entire domain "example.com"? Therefore the devices will try to connect to the new server before it is ready.

Or, does it connect to the server where the user is set up?

Basically i want to know what information does the BES send to Blackberry regarding the domains/users it contains. (How do the devices know what server to activate against)

Thanks

The BES does not "own" a domain. When you setup a BES, it does not do anything to your mail users, everything will work as before. Only when you create a user on the BES, it will handle that user.

Quote:
How do the devices know what server to activate against
Each device has service books that get created when you do the Enterprise Acrtivation. The service book contains information, which server the device is connected to (i.e. your BES server ID). So, before you activate, you create the user on the BES. Then, the user activates, which triggers a mail that is sent to his e-mail address. As this address is now handled by the BES, it can pickup the mail and send the correct service books to the device.

There is no problem to run 2 BES Server in the same windows domain.
The BES servers will know, which User belongs to which BES server.

If your migration scenario looks like this:
Add new DC with Server 2008 to the Domain, Add new Exchange Server to the domain, install new BES server, move mailboxes to new server, activate users on new BES. Remove Exchange server, demote old DC,

This should be no problem, with one exeption:
If you move a BES enabled mailbox, and, want to start from scratch:
Dont just remove the old BES, and try to activate the BB on the new server. If you do this, activation will be impossible, because the new server thinks, the user is still active on the old one.
Instead kill the user from the BES, and check the option to delete all BES related data from the mailbox. Then, move the mailbox, erase the BB handheld, and activate the User on the new BES.
After all users have been removed from the old BES server, you can uninstall/remove the old BES.
Warning: all handheld data saved profiles/wireless backup/stored passwords/settings will be lost for the blackberry users when doing this. For example, if someone stored important passwords on his device with the password keeper, the user has to make a manual copy on plain paper before the BB is deactivated.
