Lately I've been spending a lot of time on projects related to migrating traditional MPLS (based on LDP) to a new solution based on MPLS Segment Routing. Migrations can be challenging and very interesting, so I’ll try to illustrate, using the example of several clients – of course, the data will be anonymized – what the migration process looks like and what its main advantages are. I'm returning to running this blog because it gives me the motivation for further activities and learning. I hope there will be readers for what I share here and that it will be useful to someone.
Quick summary
This note is an early field-style introduction to MPLS to Segment Routing migration: why teams move away from LDP, what usually makes the migration interesting, and why anonymized customer examples can be useful for network engineers planning similar work.

Discussion
If you have performed an LDP-to-Segment Routing migration in a lab or production network, feel free to share what validation steps, rollback plan, or design notes helped the most.
This is a very interesting explanation of migrating from MPLS to segment routing – the step-by-step process and the benefits are clear and engaging.
I appreciate the insight into real-world migration projects. It's helpful to see how the transition from LDP-based MPLS to segment routing is managed and the value it brings.
Thanks for sharing your experiences with segment routing migrations. Your explanation makes the concept accessible, and it's inspiring to see your continued enthusiasm for blogging.
