Hi, I’m using the router OS version 5.23, If I upgrade to 6.XX, I lose the configuration?? I mean, I have to configure it again?
No, but you may need to readjust your queues (particularly simple queues, if that’s what you’re using).
The interface argument is removed, and the target argument accepts an interface, BUT the semantics of the old and new are not the same. In v5., having an interface + target means “this IP, if the in-interface is this one”, whereas in v6., if you specify two targets - the interface and the IP (which is how your v5 settings will be migrated as) - it will mean “this IP or any IP that comes in from this interface”. If you REALLY need to apply queues per both interface and IP (exactly as before), you need to have a parent queue matching the interface, and then child queues that match the IP needed. Only then will the interface be checked first and the IP afterwards. The RouterOS update is not intelligent enough to do THAT particular translation automatically.
