Exchange 2010 DAG: Cannot make a database copy…

When you add a copy of a mailbox database, error:
A server-side seed operation has failed. Error: An error occurred while performing the seed operation, which may indicate a problem with the source disk.
…blablabla…
Database ‘_DBID_’ was not active on source server ‘_source-server-name_’.
A copy of the GUI interface does not work, but PowerShell command is:

Add-MailboxDatabaseCopy -Identity _DB name_ -MailboxServer _targetservername_ -ActivationPreference 2

Grrrrrrrrrrrrrr…..

Upgrading Windows Server 2008 R2 without media

The supported upgrade paths are:

  • Windows Server 2008 R2 Standard -> Windows Server 2008 R2 Enterprise -> Windows Server 2008 R2 Datacenter
  • Windows Server 2008 R2 Standard Server Core -> Windows Server 2008 R2 Enterprise Server Core -> Windows Server 2008 R2 Datacenter Server Core
  • Windows Server 2008 R2 Foundation -> Windows Server 2008 R2 Standard

To determine the installed edition, run:

DISM /online /Get-CurrentEdition

To check the possible target editions, run:

DISM /online /Get-TargetEditions

Finally, to initiate an upgrade, run:

DISM /online /Set-Edition:EDITION_ID /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

WARNING: One important note, is that the server can’t be a DC at the time of upgrade. If you demote a DC using dcpromo, you can upgrade, then re-promote it (you may need to migrate FSMO roles, etc, in order to succesfully demote.)

Speed up Exchange 2010 move request

In CAS server navigate to c:\Program Files\Microsoft\Exchange Server\V14\Bin\MSExchangeMailboxReplication.exe.config file.

By default, the CAS servers are set to:

MaxActiveMovesPerSourceMDB = “5″    
MaxActiveMovesPerTargetMDB = “2″    
MaxActiveMovesPerSourceServer = “50″    
MaxActiveMovesPerTargetServer = “5″    
MaxTotalMovesPerMRS = “100″ 

You can change the settings to:

MaxActiveMovesPerSourceMDB = “15″    
MaxActiveMovesPerTargetMDB = “15″    
MaxActiveMovesPerSourceServer = “50″    
MaxActiveMovesPerTargetServer = “40″    
MaxTotalMovesPerMRS = “250″

Once changed you must restart the MRS service.

Migration process is very disk I\O intensive!
