I’m not sure if this is wise yet, but I’m hoping to upgrade some of my Mikrotik units to 6.X soon.
Is there a document that describes the differences between 5.X and 6.X and what I need to be worried about? [Other than the usual buggy slag in most all RoS versions? 
]
TIA

There’s the change log (right click and select “View Source” to see it in a nicer fashion), which can tell you most of the intended changes.
Stuff that’s not in there, including new bugs… I’m not aware of any such “documents”… Just forum posts, but then again, it’s never certain if what someone is talking about is a bug or a configuration problem. As soon as MikroTik publically acknowledges a bug, it’s fixed in the next version, so any I could dig up are most likely to be fixed already in the latest release.
EDIT: Oh, and this wiki page.
if you have done have any scripts after ssh or api it count with this that you will have to redo them, because in this case there is a lot of change and what version is cośnowego 
I did look at the change-log for 6.0 release and there wasn’t anything that indicated any real difference between 5.X and 6.X.
But has scripting changed? I have a substantial number of scripts I’ve written in 5.x and having to re-work them could be very time-consuming!
Critical pieces. IPSec and OpenVPN - have these changed substantially?
Most everything else I’m doing is pretty vanilla - so should transfer fine.
