5. Click next and then New

This will move mailboxes to Exch 2010 one by one. The mailbox that is being moved will not be accessible. This process will take a long time and depends on how fast your disk system on SBS 2003 is.

 

6. You can go to the properties of any move request to see how much time the process took

Offline Address Book

Generate new OAB on Exch 2010 and set to default.

 

 

Migrate Public folders

In this migration we have decided not to move Public folders .

However this procedure is best performed Via .PST file transfer

If this can not be performed via .PST you can try the following

  • · Open Exchange System Manager
  • · Navigate to Administrative Groups > First Administrative Group > Servers > Server name > First Storage Group
  • · Right click on the Public Folder Store and select Move All Replicas.  The only option that should appear in the list is your Exchange 2010 server.  Click OK.

 

 

Certificate

A new certificate is created on Exchange 2010 when you install it. This will be the same certificate that is installed on SBS 2003

For a trusted certificate refer : http://technet.microsoft.com/en-us/library/dd351057.aspx

 

 

Uninstalling Exchange on SBS 2003

To do this click start –>  run  –>  appwiz.cpl. This will open add and remove programs window.  Highlight Windows Small Business Server 2003 in the list and click Change/Remove.
Click next on the Welcome screen, and next on the screen that follows.  Once the component screen opens pull down the drop down next to Exchange Server and select remove, as shown below. Then click next and next again.
