As per Pankaj, below is a set of important information for design software users:-
Why is Autodesk transitioning to subscription licenses?

Subscription licenses offer customers a lower entry price, greater choice of tools and the ability to pay-as-you-go. With its shift away from selling perpetual rights to use a specific version of software, Autodesk will continually innovate and improve products and supporting services that customers subscribe to, allowing access from multiple devices at any time, making them easier to deploy and manage, and reducing file compatibility issues.
Does this affect existing software purchased under a perpetual license?

No. Existing or new perpetual licenses purchased up to January 31st, 2017, remain valid. Customers retain their perpetual software license and can continue to use it in accordance with their perpetual license agreement. All software products covered by a maintenance plan will continue to receive benefits such as technical support, the latest software release, previous version and other licensing rights, and product updates.
What is involved in subscribing to Autodesk products?

Subscribing to Autodesk products gives you access to the same full version of Autodesk software as the equivalent perpetual license – but with a flexible, pay-as-you-go approach for a software budget that is easier to manage.
Is Autodesk making any changes in terms of how I can subscribe to products?

To provide customers with greater purchasing flexibility, Autodesk has introduced multi-year (2-year and 3-year) terms for new subscriptions. This locks customers in to current subscription pricing, protecting them from any future increases.
What is a maintenance plan?

Maintenance plans ensures a perpetual license holder receives benefits such as Basic Support, options for more advanced support, and access to the latest software and product enhancements. A maintenance plan agreement must be applied to each separately purchased perpetual license.
How will this change impact customer with a maintenance plan?

Customers with current maintenance plans will have the option to renew their maintenance plan and continue receiving the corresponding benefits. Autodesk has no plans to stop offering maintenance plan renewals. However, it is important to renew the maintenance plan on time to continue to access the benefits.
