Two questions:
1.
I have a library+settings backup from a Portable install of 27.0.37. Every time, before updating a Portable install, I create a zip of the entire, current Portable install folder as a 'safety' regression point. Can I unzip back to, e.g., 27.0.26, then, restore a library+settings backup made under 27.0.37? Or, will I get a) errors when I try to use the library, and/or b) a message like 'you're trying to restore a database from a later version of the application...'?
2.
I updated a Portable install from 27.0.26 to 27.0.37. Is there anything preventing me from 'installing' 27.0.26 back over-top of 27.0.37, assuming I want to regress/revert to that version? Would this leave behind a proper/thorough regression, or would it be a hack job leading to potential issues?
Normally I would simply restore the earlier 'safety' zip and be done with it. However, I applied many networking-related and other settings between .26 and .37, so I'd like to avoid repeating all that grunt work again on three systems.
Thank you.
