Can I edit a sequence after learners are enrolled?

Yes. You can continue editing a sequence after learners are enrolled:

• Adding courses is safe — new courses will appear in enrolled learners' sequences. If a learner has already completed a newly added course independently, their existing progress will be recognised and contribute toward their sequence completion.
• Removing courses requires care — the course will be removed from the sequence, though individual course progress is still stored. If the course is later re-added, the learner's prior progress will be recognised.
• Changing prerequisites will update the recommended order for all enrolled learners going forward.

When a sequence is updated, enrolled learners' progress is automatically aligned to the current version. Individual course progress is always preserved regardless of sequence changes.
