TOS 3.11.16 to TOS 5.0.0 migration experience

I apologize for my confusion.

The steps to do this seem to be scattered and the explanations seem to be terse. I am hoping to do this with a family desperately depending on my network (including me) so I’m hoping to reduce my downtime to do this or at least prepare for when 5.0 is in HBS.

It seems comprehensive documentation on how to do this is:

schnapps import -f medkit-<some version>.tar.gz && schnapps rollback factory

Does this mean that the factory image is set to be <some version> and then “rolls back” your installation to this version? Or the factory image is the currently installed 3.x version?

It’s noted

Can what this means be broken out and the explanation expanded?
