Upgrading a Tarball installation - what files need to be preserved between versions?

[Paul Norman]

Dear Gilles and Remo,

Thank you for your replies.

Sorry for any confusion, yes I am at this point not looking at compiling 
from sources.

Looking at –

    https://docs.digikam.org/en/getting_started/installation.html#configuration-files

I see that even with a windows binary tarball "install", the application 
will use standard windows profile locations  to keep the configuration 
files.

Is there any way to ask Digikam to store these locally within its own 
folder structure?
Perhaps by using a switch on starting Digikam on the command-line or in 
a shortcut link?

Something like:

    w:\digikam\digikam.exe  /runlocal

I assumed that would be like a portable installation, and so searched 
the manual for portable,
but only brought up one search result about PNGs :-)

... So I'm hoping that it might be available in there somewhere?
As an experimental or undocumented feature?

Kind regards,

Paul
