+## Enabling Subscription Activation with an existing EA
+
+If you are an EA customer with an existing Office 365 tenant, use the following steps to enable Windows 10 Subscription licenses on your existing tenant:
+
+1.	Work with your reseller to place an order for $0 SKU. There are two SKUs available, depending on their current Windows Enterprise SA license:<BR>
+    a.	**AAA-51069** - Win10UsrOLSActv Alng MonthlySub Addon E3<BR>
+    b.	**AAA-51068*** - Win10UsrOLSActv Alng MonthlySub Addon E5<BR>
+2.	After placing an order, the OLS admin on the agreement will receive a service activation email, indicating their subscription licenses have been provisioned on the tenant.
+3.	The admin can now assign subscription licenses to users.
