I can find the documentation for Router OS v7 here: https://help.mikrotik.com/docs/display/ROS/RouterOS
Is this still the documentation for v6? https://wiki.mikrotik.com/wiki/Manual:TOC - is it still updated as v6 isn't EOL?
I'm sure I read somewhere that some devices (not SMIPS) couldn't or shouldn't be upgraded because they didn't have enough resources - can't recall whether that was CPU, storage or RAM.What is your question? The only not-supported devices are SMIPS CPU based, which are very old. Documentation is not changing, because software is not changing.
Wasn't that already answered?I'd be very surprised if the ROS v6 documentation was perfectly accurate No documentation I write is every 100% bug free...
No, bugs are also not fixed, except if they are security related.
