In order to remove an Exchange Server 2003 we must move all Public Folder to another server. In this post we will be moving the PF data from an Exchange Server 2003 to an Exchange Server 2007. After finishing the procedure that will be described in this post we can remove the Public Folder store from Exchange Server 2003.
First of all let’s replicate all the data from 2k3 to 2k7, to do that let’s add the 2k7 in the Replication tab list of all current folders of Exchange Server 2003. It will take some time and it depends how large is our PF data.
We can also see all the current PF content locally under Public Folder Store / Public Folder Instances.
Let’s move those PF to our Exchange Server 2007. We can accomplish this from different ways, on of them is running in the Exchange Management Console a script called MoveAllReplicas.ps1, as shown in figure below.
MoveAllReplicas.ps1 -Server <old-server> -NewServer <New-Server>
After that command we can check the Public Folder in the Exhcange 2003 and we will see that the replication tab has only Exchange Server 2007 on that list.
To see the operation progress, we can check the Public Folder Instances to validate that folders seen in the the same item will start to disappear, when there are not any item left on the right side we can remove securely the Public Folder store from Exchange Server 2003.
