Software Subscriptions and License Mobility

Microsoft announce that CSP Software Subscription benefits are fully equivalent to Software Assurance from 1 April, 2026.


License Mobility (through Software Assurance) allows the use of eligible licences in Azure or on an Authorized Mobility Partner’s shared hardware and has long differentiated the two purchasing options. The change expands this outsourcing option to SQL Server, and the External Connectors for Windows Server and RDS. Of particular interest, Listed Providers Amazon, Google, and Alibaba are currently signed up as Authorized Mobility Partners.

Although System Center Server is also available as a Software Subscription, it’s somewhat neglected in the announcement, even though its Software Assurance counterpart has always been eligible for License Mobility.

Microsoft provide us with a range of resources to supplement the news.

Software Assurance resources

We’ve uncovered some useful and updated Software Assurance resources.

The Program Guide update includes typo and formatting corrections, while cleaning up (some!) references to the obsolete Windows To Go benefit. However, many of the previous Cautionary Notes are still lurking. The FAQs document features general Software Assurance questions and more specific benefits like the Workplace Discount Program and Flexible Virtualization Benefit.

Exclusively for subscribers, our Licensing Guides Gallery (https://bit.ly/GuidesGallery) outlines all details of the changes to be aware (and wary) of.

Software Assurance Program Guide

We’ve recently discovered an updated(!) Software Assurance Program Guide. It’s the first in a few years, though it could still use a few updates, as there are references to discontinued Software Assurance benefits and products. As always, a record of the quirks can be found on our Licensing Guides Cautionary Notes page: https://bit.ly/LSLVLGCN.
