Today, I'll be talking about Windows Small Business Server (SBS) 2003 Transition Pack which allows you to smoothly migrate to full blown version of windows server products.

As your business grows, you may feel the need for change and at the same time want to protect and preserve what you already possess. By installing the SBS 2003 transition pack; you can upgrade your SBS 2003 to a full blown Windows Server 2003 Std. edition, with std. version of server applications like Exchange, ISA and SQL.


Things you can achieve after installing the transition pack

You can achieve the following task after installing the SBS 2003 transition pack, which otherwise is not possible in SBS 2003 because of product design limitation.

- Transfer the Flexible Single Master Operations (FSMO) roles to another domain controller

- Establish two-way trust relationship with another Domain

- Add child domains to the existing AD forest

- Move server applications to another server (for e.g. You can move Exchange Server 2003 to another server for better performance)

- Enable Terminal Server in Application Sharing mode

- Remove the 75 users/device limit

- Increase the max number of processors supported from two to four



After you have migrated your server by installing the SBS 2003 Transition Pack, you will still be able to use the Windows Small Business Server (SBS) 2003 tools; however, they will no longer be supported and you will not be able to reinstall or remove the tools. Additionally, you will no longer be able to run Windows Small Business Server 2003 R2 Setup to modify (add, remove, re-install) the server applications.

After you migrate to Windows Server 2003 R2, Standard Edition, you must reinstall your existing Windows Server 2003 service packs. In addition, you should record the current built-in Administrator account password for reference because the Directory Services Restore Mode password will no longer be synchronized with the built-in Administrator account password.


Checklist before installing the Transition Pack

Make sure you have ordered for the fulfillment media for the standard versions of applications (This media is required if you want to move applications to a new server and will also help for system recovery) before you install the SBS 2003 transition pack.

What happens after you apply the transition pack

The following snapshots would help you understand the difference between SBS 2003 and Windows Server 2003 (the way SBS 2003 looks after a successful installation of Transition Pack).


Before the Transition Pack After the Transition Pack
This is the first difference you would notice after a successful installation of SBS 2003 Transition Pack. The SBS 2003 logon screen is replaced by the Windows Server 2003 logon screen.
Diff11 Diff1
WINVER clearly shows the difference between SBS 2003 and Windows Server 2003 Std. Though the build number, service pack details are still the same.
Diff22 Diff2
The product ID (PID) for SBS 2003 is changed to a Windows Server 2003 PID. The SBS 2003 PID starts with 74995. The Windows Server 2003 PID typically starts with 69712.
Diff33 Diff3
If you double-click the Licensing icon in control panel, this is how it looks before the transition pack. You use the Server Management console to install licenses on SBS 2003. After a successful transition, you should be able to add additional licenses for std. line of server products like Windows, Exchange from Control Panel.
Diff44 Diff4
Terminal Server in Application Sharing mode is unavailable in SBS 2003. You cannot have more than 2 concurrent connections to the server. After the transition pack, you have the option of running Terminal Server in Application Sharing mode.
Diff55 Diff5
The option to "Manage your server" is not there on SBS 2003. After a successful transition from SBS 2003 to Windows Server 2003, you get an option to "Manage your server" under Administrative Tools.

Issues you may run into after or during the installation of transition pack

Scenario 1:

If you running Veritas Backup Exec program on the server, the Transition Pack installation may fail silently

Resolution: Look for the registry key Small Business (under HKEY_LOCAL_MACHINE\Software\Microsoft\). If the key exists, delete it after taking a backup of it.

For more info:

Scenario 2:

Server stuck in an activation look after installing SBS 2003 Transition Pack. This issue typically occurs if you running IE 7.0

Resolution: Boot the server in Safe Mode. Uninstall IE 7.0 by executing the following command from the Run dialog box


For more info:

Scenario 3:

Service pack mismatch problem. You may get an error stating that the installed version of the product is newer than the current installation.

Resolution: You want to make sure that the service pack matches before starting up the process. If you running Windows Server 2003 SP2, uninstall it before installing the transition pack. Additionally,  make sure that you are using the SBS 2003 with SP1 Transition Pack media.

For more info:;


Kinds of Transition Pack

Like SBS 2003, transition pack comes in 2 variants, SBS 2003 Transition Pack and SBS 2003 R2 Transition Pack.

The SBS 2003 Transition Pack includes 1 disc which allows you to convert SBS 2003 to a full blown std. version of Windows Server 2003

The SBS 2003 R2 Transition Pack includes 2 discs. The first disc is the same as above which allows you to convert SBS 2003 to a full blown std. version of Windows Server 2003. The second disc is the Windows Server 2003 R2 disc and has features like DFS-R.

Don't forget to read my second post on Transition Pack.

  • Moloy Tandon's Blog - Ask Me : SBS 2003 Transition Pack

  • After applying the transition pack. We lost client access to the \companyweb.  Have not been able to figure out how to get it back.

  • Please refer to Scenario 1 - Method 2 of the KB 940194 for the resolution.

  • Has anyone got any good migration plans (preferably more specific, less "big-picture" as I am not a wonderful exchange/isa/sql guru) after the transition pack has been applied for Exchange/ISA/SQL from SBS 2003 Premium to be migrated to seperate windows 2003 boxes please?

    Thanks in advance for any suggestions/pointers.

  • Is there at transition pack specifically for migrating to Enterprise?  Or, must you first migrate to std edition then upgrade the installation to enterprise?  I was going too do a fresh install on new hardware supporting dual quad core Intel + 8 GB RAM with enterprise version with Exchange 2007 and then migrate AD and mailboxes seperately...any white papers on this scenario..or close?

  • So, after backing up the registry key in scenario 1 and deleting it, the upgrade should run fine. Once the upgrade runs, is it ok to put the key back?? Thanks!

  • I would like to move Exchange Server and ISA 2004 to a seperate server and keep everything else on the old SBS (Now 2003 R2) server.

    I assume that the Exchange Server would have the 2 NIC cards with the WAN and LAN cards and the ISA 2004 to filter at the source.  The last operation would be the exchange server.

    Would anyone wish to comment to this arrangement?  I thank you in advance and am glad I fould this site.  There appears to be precious little info on transitioning from SBS to regular WIN 2003.

    thanks,  Tad Sendzimir

  • Is it possible the following migration scheme:

    SBS 2003 STD -> 2003 STD -> 2003 ENT


  • Yes, its possible.

  • I am applying the SBS R2 Transition Pack.  I am wary of the process, as I have never applied a transition pack before.  Will all data remain the same (users, emails, etc) after applying the transition pack?

    Also, I'm looking to migrate Exchange to it's own server during the transition.  Do I need to set it up on the new server then migrate the data, or is there a step for the migration during the transition pack installation?

  • I have a small buisiness server installed i want to backup Active Directory from it and restore it on a server running Enterprise edition.Is it possible please try to email me or post it here with all the steps required.

    please please

  • @eyoel getachew

    Restoring the system state backup on a different hardware is not supported.

    Your options are:

    1.) Use the ADMT tool to migrate from SBS 2003 to Ent. edition of Windows Server 2003.

    2.) Use the transition pack to convert SBS 2003 in a full blown Windows 2003 Server Std, Exchange Std, etc. and then upgrade it to the Ent. edition of Windows Server 2003.

    3.) Join the Ent. edition to the existing SBS 2003 AD domain and then migrate all the data across.



  • In my previous post about the Transition Pack , we talked about the Transition Pack and the changes it

  • Thanks for the info. I would like to move Exchange to a seperate server. Should I install Exchange on that particular server before applying the transition pack? Is the exchange media on the transition pack disc or could I install it from the original SBS disc set?

  • Hi there, can you please advise what are the differences between these 2 packs? I got a SBS 2003 Premium (non-R2), am looking at transitioning it to Win 2003.
