I have a client running Catalina on an old 2013 iMac with a spinner. =
There's no reason he needs to be running Catalina (he still uses Lotus =
123, for heaven's sake), he is apparently just a low-information victim =
of Apple's antisocial robo-nag campaign to "Upgrade! Upgrade!! =
Upgrade!!!"=20

His machine is now crawling.

My preference would be to clone his machine to an external, wiping it, =
install  fresh High Sierra, and then migrate his files back in. But I'm =
unsure whether there have been format changes between HS and Catalina in =
personal databases such as Photos, Address Book, mailboxes, and the like =
that would queer this=E2=80=A6 or whether File Migration might just =
arbitrarily nix the importation out of principle. Not to mention knowing =
that the System Settings category (WiFi networks, Apple IDs, Sharing, =
Accessibility, etc.) would probably be un-migratable in toto, but that's =
less important as it can be addressed manually.

Can anyone say if this reverse-migration is doomed before it's tried?

The alternative would be to swap out his HDD with an SSD and clone it =
over, which would be a more costly job in terms of hardware fiddlery =
time (I hate working on iMacs, having to disconnect all the fragile =
display screen connectors to do the simplest things), pus the cost of a =
new TB drive.

(Damn Apple's irresponsible pressure on typical consumers to upgrade =
their OSes.)
