CRS354-48P-4S+2Q+ replacement issues

I have a CRS354-48P-4S+2Q+ that occasionally fails and need to be rebooted to work. It is heavily configured. I only have one in this location. The person that configured it quit, and a week later its started to fail. I am not up to speed on these routers and thought I would just back the old and restore onto the new. ut the interfaces are very different. Here is the info from both. Is it possible to do what I need, or do I have to slog through and figure it all out ?

First off: CRS354 (the whole CRS family of devices as a matter of fact) is a switch not a router. Yes, if running RouterOS, it can route and if carefully configured, it can route at wirespeed (if not carefully configured, it can route at very low speeds, like 200Mbps cumulative between any combination of ports).

Secondly: based on output you provided, the old device is running SwitchOS … and the new one is running RouterOS. If you want to replace the old one with the new one running (more or less) identical configuration, it would be easiest to switch the new one to using SwitchOS (while device is running RouterOS, change setting /system routerboard settings set boot-os=swos and reboot device … it should come up in SwitchOS after that).

As to migration of configuration from old to new: I’m not very familiar with SwitchOS, but AFAIK it doesn’t have any “configuration migration” facility. So you’ll have to manually (from configuration screen to screen) copy settings from old to new.
