How to transfer Office 365 client from advisor to CSP in 4 easy steps

As a reseller, you’ve probably heard all the talk about converting licenses for Office 365 to Microsoft’s Cloud Solution Provider program (CSP). You might have read about the multi-channel feature and how you can use it to transfer existing client subscriptions for Office 365. You might even know that you can add tenants from other reseller programs, such as Microsoft’s Open and Advisor. But, when it comes right down to it, do you really know how to onboard customers as a new CSP partner? We’re willing to bet that you have a few questions. If that’s the case, we can help. Take a look at this quick guide that shows you an easy way to transfer client subscriptions from advisor to CSP program with SherWeb.


SherWeb or Microsoft? Learn which partner will help you go to market faster with Office 365.


Step 1: Create your client account

Log into Cumulus, SherWeb’s partner portal, to create your new client account. Type in the client’s name and contact information. Cumulus is SherWeb’s one-stop shop portal that gives partners access to many product lines, such as cloud servers, hosted Exchange, Office 365, online backup and more.


Step 2: Select the Office 365 plan

As shown in the screen below, select the product line (Office 365 in this case), the plan and the number of licenses you want. In the Platform Settings tab, add the client’s tenant address and indicate that this is an existing tenant. It’s important to note that the address must end in .onmicrosoft.com. Add this to the Cumulus account and press Save Changes.

Step 3: Activate invitation to join CSP

Enter your Office 365 client’s current tenant address. Click on authorize Sherweb Inc. to be your Microsoft Cloud Solutions Provider (CSP) to generate an approval link.

  • If you know your customer’s Office 365 tenant administrator credentials, click on Sign in when prompted to authorize you as a CSP.
  • If you don’t know your customer’s credentials, copy the authorization web page URL and send it to the client so he can log in and authorize you as a CSP.

Step 4: Accept invitation to CSP

Click on the approval link and log onto Office 365. You’ll see a screen with a headline that says Accept Microsoft Cloud Solution Provider invitation. Check the box and then click Authorize CSP to accept the invitation.

Finally, back into the Cumulus Partner Portal, click on Validate authorization.


100% seamless – no migration required

It’s important to note that this transfer won’t affect your clients’ existing subscriptions. License conversion used to be a lot more complicated. Before this feature was introduced, resellers had to create a new tenant and do a full migration for each conversion. The new process has been streamlined so that the end user won’t even be affected. There is no technical migration required and the client won’t experience any downtime.


Make sure to remove the old subscriptions

Once the subscriptions are transferred and the licenses are added from advisor to CSP program with SherWeb, you should remove the old ones and close that account. If you want to upgrade or downgrade these licenses after, you can do it in Cumulus.


Choose matching licenses for each user

When you’re transferring client subscriptions, make sure they match for each user. For example, you can’t transfer a Business Premium license to an E3 license using this process. As we already mentioned, you can do the upgrade later in Cumulus. If you have any trouble, SherWeb’s migration team is always available to help you.

Microsoft introduced the Cloud Solution Provider program last year to respond to partners’ requests to get more involved in the customer sales cycle for Office 365. Under the CSP program, partners have complete control over customer renewal, billing, provisioning and support.
