Starting November 2, 2020, Autodesk is expanding version access for all customers (on subscription and maintenance plans) for the latest release and up to 5 versions back.
All Autodesk customers on subscription and maintenance plans now get access to up to 5 previous versions, including customers who are trading in their multi-user subscription or maintenance plan for a named user subscription. After trading in, you will be able to access up to 5 versions back from the latest release of your product.
You can access the latest version of your product and up to three versions back within Autodesk Account. To access up to 5 previous versions, contact the Autodesk Virtual Agent (AVA).
Please note, although Autodesk is expanding access to 5 versions back, only the current and 3 versions back will be eligible for Autodesk technical support.
