About this task
When upgrading from SDL Trados Studio 2015 or 2014 to Trados Studio 2017, your original license will be automatically removed from your account. To continue using the older version alongside Trados Studio 2017, you should consider purchasing a full license instead of an upgrade.
Refer to the SDL Trados Studio license upgrade process KB article for details on older versions of Trados Studio license upgrade paths.
