Workfront Ascent will continue to be the source of training for Workfront Classic. Workfront One is the host for all new Workfront experience training.
If you're not onboarding users into the Classic experience, you won't need Ascent access for them. In fact, we have a page specifically for onboarding new users on Workfront One -- the Getting Started page. The learning paths here are designed to give new users the "fundamentals" of Workfront so they can get up and running!
Then additional training is available on the Training page. The learning programs are similar to the programs on Ascent—a collection of courses (learning paths) on a specific topic. The learning paths are similar to courses in Ascent—training on a specific feature, topic, etc.
Don't forget to click the Additional Resources tab to access the video library, downloadable guides, and learn about boot camps.
