I'm relatively new to production Mikrotik deployments and I'd like to know how reliable are RouterOS updates. When a new version comes in stable or long-term channel, is it safe to update remotely? It would be very inconvenient for me to travel all the way to the site and bring the device back online. Have you ever had a case when you updated RouterOS and after the reboot some things weren't working anymore? What is your update policy?
