1.1 What is changing for customers with maintenance plans?
We believe that subscribing is the best way for our customers to get the greatest value from our tools and technologies – and will fundamentally change how we deliver extended capabilities and new functionalities through connected services.
Beginning in June 2017, customers with eligible products on maintenance will have the ability to easily switch to a subscription at the time of renewal for up to 60% less than the cost of a new subscription. Customers can take advantage of this offer once per seat of a product on maintenance. The price to switch will increase 5% in 2018 and another 5% in 2019, so the earlier customers switch to subscription, the less it will cost. For more information on this offer, see Switching from Maintenance to Subscription.
While we will continue to offer customers the choice of renewing their maintenance plan on an annual basis, effective February 20, 2017, multi-year maintenance plan renewals will no longer be offered. In addition, because managing two business models (subscription and maintenance plans) is quite costly, in order to continue supporting maintenance plans, beginning May 7, 2017, maintenance plan renewal prices will increase by 5% in 2017, 10% in 2018, and 20% in 2019.
1.2 What are my options when my current maintenance plan comes up for renewal?
When your maintenance plan comes up for renewal, you will have 3 options:
Switch your individual product on maintenance to a subscription of the same product
Switch your individual product or suite on maintenance to an industry collection subscription
Renew your maintenance plan for one year
1.3 Will these changes affect all Autodesk customers?
These changes will affect customers with Autodesk products on maintenance plans, but will not affect subscriptions to Autodesk products.
1.4 Will I be able to continue renewing my maintenance plan?
Yes, if you choose to stay on maintenance, you will be able to continue to renew your maintenance plan/s on an annual basis.
1.5 Are the maintenance plan changes global?
Yes, the changes are global.
