Default Exchange 5.5 -> 2K3 Migration

Please Login to Remove!

Hello All,
First off, let me state that I am in no way a Blackberry Admin.

Now, here's my situation.
I was brought in to upgrade this company to Active Directory (from an NT4 Domain) due to the fact that their Exchange 5.5 system is hitting the size limitations.

So, created the new Active Directory (Win2K3 Server - Win2000 Compat).
Built the new Exchange 2003 Server (on a Win2K3 Server).
Have migrated all of our users to the new server already and have been trying to migrate the BES Users with no luck.

They set up their BES to use the NT4 Domain Admin as the BES Admin; however, I cannot migrate the NT4 Dom Admin to the Active Dir of course.
Migrated the BESAdmin User from the NT4 Dom to the AD and applied all delegations and permissions to the necessary storage group, server, etc (went overboard here...actually gave full admin rights to the entire exch org).

BES is currently running on the same server as the Exch5.5 Server. Can I migrate all of the BES Users to the new server without decommissioning the Exch5.5 server? (I tried and all seemed to work like a charm, except the last connect time simply always shows the time prior to the migration of the users).

Since it didn't work, I have since migrated the users back to the original Exch 5.5 Server again.

Good to know. That said, if you get confused / stuck through this process ... spend the money and get RIM's T-Support on the phone. For the price, it'll be the smartest decision you'll make before you do something that requires every device to re-activate or something like that.

This is absolutely a migratable (I think I just made that word up) situation.

Back the permissions down and just put in what is required. More permissions will not help; they will only cause trouble.

Eh ... not really. You need the MAPI components on the BES to be at or above the version that the mailbox server being used is at. Since all the users will be on 2003; you either need to:

1) Create a new BES somewhere else and migrate the users to that
or
2) Uninstall Exchange 5.5 and then install the Exchange 2003 System Manager / patches / service packs to match the new 2003 server.

Lastly, what version of BES is running on the Exchange 5.5 server?

Give these a review too:

I agree with everything hdawg as said. I don't have any of my notes with me on the pitfalls that I landed on, but the method above looks very much like what I did when I was in your situation.

I will also say, that TSupport is HIGHLY recommended. They will practically do it for you. Hell, they WILL do it for you. They are great.

Thanks for the replies too. I like how you broke it down.

Versions
Blackberry Mgr - 4.1.5.26
USB Channel Controller - 4.0.0.1
Device Mgr - 4.3.0.7
Application Loader - 4.3.0.17
RIM Intel Programmer - 1.0.0.35

Couldn't figure out exactly what BES Version it was (saw how to find that on the forums here Saturday, have to look it up).

OH I belive it, as it is like that with so many things here in general
I see the link regarding the move of the Administrative Mailbox - With the mailbox being linked to the NT4 Domain Admin - Can I change this to be BESAdmin? - I really don't want a mailbox named "Administrator".

Review this post: http://www.blackberryforums.com/bes-...e-running.html

you can absolutely move the mailbox to something else; it shouldn't be Administrator. Just follow the procedures.

Since I'm finding all this so helpful...

The current BES/EXCH Server is in the old domain.
I want to rename the server and place it in the new domain -- Will that cause any problems? I see where it might cause problems with the server name (SQL Server 2005 Express).

I see that the User Name for the Keystore File is set to match the name as the current Domain Admin (just as the name not domain\name format) - will this be any sort of problem?

It'll squawk at credential changes; but you can move servers as long as they're in the same forest. Then you'll just have to update anything that uses credentials you've moved ... and of course make sure any permissions while the server is in domain A are there when in domain B.

SQL has ways to handle server renames / domain moves ... google for it; I actually just did a sql move / rename last week and it went quite smoothly.

I think that'll get taken care of anyway when I move to using Domain\BESAdmin instead of having everything use that domain's admin acct.

What about that Keystore name? Is that just more or less a string text name where it really does not have to be dealt with in a domain move?

Thx Again
