As most of you will probably know just from looking at the new Exchange management console it isnt quite as easy as copying and pasting the priv1.edb or Exmerging in and Exmerging out the old data.
The techniques are now slightly different:
Although the method is the same there is a slight change if you are doing this for a Server 2003 with Exchange 2007 or an SBS 2008 with Exchange 2007. If you are runnning SBS 2008 then you must download the Exchange Management Tools and the Windows Powershell add-on from the Microsoft site and run this on a 32-Bit machine seperate to the SBS box. (Please note that if you are doing import mailbox procedures then you need to download Exchange 2007 SP1 from the site)
So first step then is the data extraction; from 2003 this is very basic and straight forward using Exmerge from Microsoft you can take out all of the previous mailboxes into PST's and store them on the new server.
The second step is to go into the Exchange management shell and enter the following commands bearing in mind that all scripts are case sensitive.
Grant the Administrator Account full access to all Mailbox's:
"Get-Mailbox | Add-MailboxPermission –user Username –AccessRight FullAccess –Inheritancetype all"
Begin the import procedure for all users
"Get-Mailbox -Database “SERVER\Mailbox Database” | Import-Mailbox -PSTFolderPath
This will then go through the motions for importing all of the pst files into their correct user accounts.
If you want to look at importing an individual mailbox to an individual user then the process is again very similar but the command is as follows:
Typing -whatif at the end of a command in Exchange powershell runs a simulation of the command without actually doing anything with the data.
