With the time running so fast, you won’t even realize that you are approaching towards the low available space issues in your Exchange server mailbox until an alert pops up on your screen. This issue needs quick remediation so as to ensure the zero-data loss. You have two choices at this stage either to go for the migration or upgrade your server to a newer version.
Before you pick any of the above stated options, it is very important to understand that any Exchange Server Migration/Upgrades is incomplete until you decommission the previous Exchange Server completely from your system. The reason that makes decommissioning an important practice for Exchange Server Upgrade or Migration is the orphaned objects that are often left behind from the older versions and disrupt the functioning of new ones

What Decommission means to Exchange?
Decommission, commonly referred as un-installation, and is considered as easy as removing just any software from your system’s memory using Add or Remove Programs facilitated to every user. But the fact is complete reverse. It is a complex process that involves a lot of changes to the system, which if continue to exist will only leads to regular functional issues like extension of Active Directory (AD), creation of new user groups, change of registry keys (HKLMSystemCurrentControlSetServices and HKLMSoftware), modification of configuration information, creation of new user groups in Active Directory (Microsoft Exchange Security Groups), and much more.
Note: It is recommended not to use similar Exchange 2010 server names and IP addresses unless the Exchange Server 2010 is decommissioned.
Manual Method of Exchange Server Decommission
Therefore, it is better to go for the manual process of Exchange Server Decommission in order to continue working with the newer version smoothly.
It is to be mentioned that the Exchange Server 2010 Decommission process involves these multiple processes once the user mailboxes and public folder databases are successfully backed up and migration to the destination has been taken place.
- Stop using the Exchange Server 2010 for at least 2 days (1 week or 2 is recommended)
- Remove Public Folders from Public Folder Management Console in the Toolbox.
- Remove user mailboxes from the Exchange Management Console.
- Use this command in the Exchange Management Shell to remove the arbitration mailboxes.
Get-Mailbox -Database -Arbitration | Remove-Mailbox – Arbitration –RemoveLastArbitrationMailboxAllowed
- Remove Public Folder database and mailbox database from Server Configuration>Mailbox location in the Exchange Management Console.
- Remove Offline Address Book details from Organization Configuration>Mailbox>Offline Address Book tab location in the Exchange Management Console.
- Finally, uninstall the setup of Exchange Server 2010 from the Control Panel of your system.
- To remove the Exchange Server roles, run this command in the Command Prompt as an administrator.
setup.com /mode:Uninstall /roles:HT
Note: Use different annotations for different roles. Above we used HT for Hub Transfer role.
This manual procedure may happen to be a difficult deal to crack especially for the users who lack technical expertise or knowledge about the Exchange Server 2010 environment.
In such a scenario, Exchange Server recovery tool is the last resort that eases the entire process of migration or upgrade for users without worrying about the changes occurred due to un-installation of the previous version.
