SharePoint 2010/2013 Multi-Tenancy: Delete an existing tenant and create a new tenant and assigned same OU

Delete an existing tenant and create a new tenant and assign same OU:


Delete tenant means delete subscription ID from farm. In share Point 2010 Every Tenant is having its own unique subscription ID.

Its quite difficult to remove connection between Subscription ID and OU.On this I did some R&D and found that if you remove subscription ID from farm all connection to OU will not deleted means some entries still present in related DBs. So until you remove all the entries from share Point DBs you cant use same OU for different tenant/subscription ID. Microsoft never advise to make changes in DB directly, but I did that and it was successful. If you don't want to get this process I have a new trick to do this.

*Don't delete Subscription ID

*Just delete all the site collection present in this.

* Assign this subscription ID to new tenant.

In this way You can easily assign subscription ID to new teanant with same OU connection.


Scripts are as below:

// This will give you all subscription ID
$sub = get-spsitesubscription

//Dont use this command:

remove-spsitesubscription -identity "$sub"

//Delete all the site collection manually from centraladmin or use powershell command related to subscription ID

Try the folowing ps script to create new Tenant and can use original ( previous) OU:

Add-PSSnapin Microsoft.SharePoint.Powershell -EA 0

//Note down your scubscription ID which you want to use and we will use later in the script.


Add-PSSnapin Microsoft.SharePoint.Powershell -EA 0

*You require SharePoint 2010 SP1 because SET-Sitesubscription powershell command run only SharePoint 2010 SP1 and later version.  

You can also use same concept for SharePoint 2013 :)  it works with that too...
