as stated I would like to upgrade Office 365 Home Premium to Office 365 Pro Plus.
this is to support BYOD, so no volume license, Just a single user with multiple devices wanting to sync documents. the primary reason to consider upgrading is Pivot Table and BI analysis.
What is the annual cost for Office 365 Pro Plus, single user?
can the cost of Office 365 Home Premium be applied to Office 365 Pro Plus
What are the steps to Upgrade from Office 365 Home Premium to Office 365 Pro Plus?
