You can use the Groups and Enrolment rules to assign the 2nd course once the first is completed however it would probably happen way before they due to complete the 2nd course...sadly there is no way to schedule to rules to assign learning at a specific point in time.

You can use 2 certifications; I that does not renew and the 2nd that allows the user to RENEW their certification (the LMS will archive the previous course completion and re-enroll them so they can take it again. There are issues with this process as well since the RENEW option becomes available immediately after they have completed it the first time; again we need this to be time sensitive and have the RENEW option only appear at a specific time.

you can try it out and see if that may work for you.

There are supposed to be some improvements to the cert app coming soon so if you are not behind a deadline, you might want to wait to see what those enhancements are.

@Nicolo Malinverno another example that would likely benefit from the upcoming enhancements 

Under the current system capabilities, you could do something like this:

1. I’m assuming there’s no ecommerce involved in this.
2. I’m assuming you have access to an automation tool like Docebo Connect, Make, N8N, etc. and can use the Docebo API.
3. User completes course A and receives a Course A certification good for 11 months.
4. Since the certification expiration notices are not course-specific, be sure that the wording of any user-level certification expiring messages from the LMS is very generic (or don’t use them).  
5. If you need to keep course B hidden from the students until a particular window of time (probably to coincide with the issuance of the certification expiration messages) you can use a catalog with a group.  Membership in that group can be automated. You can either do that through manipulating a specific user additional field or (better) by creating automation that will respond to a well-crafted certification expiration notification (one with enough information structured well for automation) sent to a special dummy Power User with an email address that is the email address of a “mailhook” you’ve set up--adding that student to your group. (Amazingly there’s not a webhook that works for this or it would be far simpler.)
6. If you’re going to notify a dummy Power User of the certification expiration, you could use automation to also generate a custom certification expiration notification that applies to just Course A and provides a direct link to Course B (that they can now see because of step 3 above).  
7. For course B you could set up a normal certification with an annual expiration.  However, be aware of how Docebo displays multiple completions if you are using eLearning courses, and whether this meets your needs for how course B is displayed in transcripts (AKA “my activites”).  For our company’s needs, we need every course completion (not just the most recent) to show up under the courses tab, so we end up creating a separate Course B 2024, Course B 2025, Course B 2026… and word our certification expiration messages very generically (with a link back to the catalog instead of the expiring course).
8. TEST TEST TEST
9. Hopefully the upcoming enhancements will make most of this a temporary fix.

I would love to see things land on your point #9, @elamast!

@Nicolo Malinverno, curious if you can speak on this chaining effect on certs with related courses (or LP’s), and whether our analysis includes this type of use case within upcoming Certs/Retraining refactoring. Can you speak on any details, small or large?
