[GNC] Correct way to update/upgrade GNUCash?

[LSP]

Hello everyone,

I'm a new user of GNUCash and have a basic but essential question:
I see that GNUCash is still a traditional software installed through a
setup file instead of through the Microsoft Store.  As a result, is there a
best, aka correct, way to update or upgrade GNUCash from version A to
version B?

I mean, for traditional software installed through a setup file, there seem
to be three approaches to upgrade/update the software, but there is no
consensus:

A. Uninstall the current version, eventually reboot the computer, and then
install the new version.

B. Do NOT uninstall the current one.  Instead, run the setup file which
will replace the current version with the newer one.  If the current
version is uninstalled, some user configurations or data will be lost.

C. Does not care.  Either approach A or B is fine.

I've looked through the FAQ and a one-year archive without finding my
answer. Could someone please add this information to the FAQ?

Thank you! 😊
