Migrating Blackberry (BES) to Exchange 2007

Using Blackberry in a mixed Exchange 2003 / 2007 environment

 

Let’s take it we’re starting from a base of having M2k3 installed with MS EXCH 2003 and M2k7 installed with MS EXCH 2007. In addition to these we have a BES server.

 

Our clients mailboxes are stored on 2003, MAPI points to 2003 and 2007 is hosting a stack of accounts for people who don’t use blackberries. To use a mixed mode pending full migrate with minimum down time do like so…

 

1.       1. Ensure BES can see each mail server (ping is enough)

2.       2. Using the cmdlet, ensure appropriate rights are configured on the 2007 server for user BESADMIN

add-exchangeadministrator besadmin -role ViewOnlyAdmin

3.      3.  Add additional rights

get-mailboxserver YOUR_MAILSERVER_NAME| add-adpermission -user besadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

4.       4. Move the BESADMIN mailbox from 2003 to 2007 using the Exchange Management Console

5.       5. Restart Blackberry Controller Services in services console on BES server

6.      6.  Check MAPI config on BES server – it should now be pointing to the 2007 server

7.       7. Confirm BB users can still send / receive mail

8.       8. Move BB user mailbox from 2003 to 2007 server and confirm as above
