License update required for v4 upgrades within 72 hours
Upgrading procedure for all devices:
- Update the Bootloader if using a RouterBOARD
- In your RouterOS v3.25 or newer, Update your RouterOS license
- Upload new RouterOS v4 packages to the router, and reboot
If you are currently running an older version of RouterOS, where license can't be upgraded to the new format, you can still upgrade, but absolutely make sure that After successful upgrade click on the "Update License" button in Winbox and make sure the new license is accepted. You will have 72 hours to do this, but it's recommended to do this immediatelly
