Which command checks for RouterOS package updates and upgrades to a newer version?

• A. /system package update check-for-updates
• B. /system package update set channel=stable; /system package update check-for-updates; /system package update upgrade
• C. /system package update upgrade
• D. /system package update set channel=stable; /system package update upgrade

Answer: (B)

Setting the update channel to stable, then checking for updates, and finally upgrading is the complete, safe workflow to move to a newer RouterOS version. First, choosing the stable channel ensures you pull from the vetted, production-ready release stream rather than a testing one. Next, checking for updates refreshes the available package list so you know exactly what version is ready to install. Finally, performing the upgrade applies that newer version to the system. If you only check for updates, you learn what’s available but don’t actually install it. If you only upgrade, you risk upgrading from an uncertain or incorrect channel or without confirming what’s ready to install. If you set the channel and upgrade without a prior check, you might still upgrade, but you skip the explicit verification of what versions exist and what will be installed, which is less disciplined.
