It's stable. It's stable for ages. I don't see the need to upgrade unless the customer wants new features or Juniper recommended for an upgrade. There are so many releases. I was even using a tail release myself before advising customer , and it was stable. Even though they are end-of-life, So, the MX series is stable. Many customers are still running it, even legacy versions. The MX series offers flexibility. You can automate, configure manually, or do whatever makes your engineers' lives easier. I haven't faced any major issues myself. The main issues I've seen have been customer configuration issues. Sometimes, customers don't upgrade their hardware when necessary for certain features. Other times, customers configure things incorrectly. For instance, I might ask the customers to configure something for DevOps, but they forget to disable it. I even try to remind them in emails, but they still forget. That's when they start experiencing issues. Otherwise, there are no problems with the console.
