Are You Ready to go through the Migration Guide?

So, the HMC to Exchange Server 2010 SP1 migration guide is out. You are eager, you are planning, you are excited. Let's do it.

Starting from next week onwards for the next 1-2 months, I will be walk through the migration guide and will be discussing on some of the planning activities and etc. on this topic. I will take one of my test environments, execute the migration steps accordingly. So, hang on tight, folks.

If you are interested to walk through this together with me, the first thing you need to do is to prepare yourself a HMC 4.5 environment in your test lab and provision bunch of users in it. Your HMC 4.5 environment should have a minimum of,

  1. MPS Engine
  2. MPS Front End
  3. MPS SQL Server
  4. Exchange 2007 SP2

We will talk about what do you need to configure for the mailbox migration as we go.

Let's walk through this together. 🙂

    Hi Liquid,

    Im currently testing to migrate our testing eviroment HMC 3.5 to Ex2010SP1 hosting using this guide. I was successfull to the point where i had to use script "PrepareOrgMailboxes.ps1".  

    Script give me this errors for every user:

    forceMergeObject : Error updating local MEU(,OU=Test50,OU=Microsoft Exchange Hosted Organizatio

    ns,DC=hosting,DC=local) attributes from source object. Please fix the error and run this script again. Error: Exception

    calling "SetInfo" with "0" argument(s): "The attribute syntax specified to the directory service is invalid.


    At C:TempScriptsE14-ImportPrepare-MoveRequestHosting.ps1:1278 char:37

    +                     forceMergeObject <<<<  $recipienttype $localOU $localCU $localusr $srcObject

       + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException

       + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,forceMergeObject

    Any idea?

    Yeah, i figure it out. I recomend to use script Prepare-MoveRequestHosting.ps1 or Prepare-MoveRequest.ps1 from instalation directory of Ex2010 SP1. Do not use that one from "". Or use Prepare-MoveRequest.ps1 script with parameter "-UseLocalObject -OverwriteLocalObject" .

    The Prepare-MoveRequestHosting.ps1 script doesn't copy the legacyExchangeDN and ExternalEmailAddress attribute. Do you have idea what is the problem
