Hello,
I know that there isn't a supported way to upgrade Debian through new OS
versions that package new perl releases other than doing a parallel
install or reinstall, but I have an older fork of netdisco that has been
massively customized (and we stalled out on trying to merge patches back
into the mainline many years ago).
Is there any theoretical way to allow such an install to survive
upgrades? I'm trying to run a PoC on some integrations that require me
to have upgraded libraries past what I have available to me and am
looking at having to undertake a massive multi-server rebuild to even
get started...any hints or help getting Debian upgraded and fixing the
Netdisco install to work with the new perl would be appreciated!
I'm hoping in the long-term to be able to re-merge the changes back into
the Netdisco main branch, but I don't have the resources for that right now.
Thanks!

I'd try like that:
1. have a full working backup of the old Debian
2. do one or more major version upgrades to the distro
<https://wiki.debian.org/DebianUpgrade> until you're at the latest release.
3. rename your old ~netdisco/perl5 to ~netdisco/perl5.prev
4. Install a new version of Netdisco as shown here:
https://metacpan.org/pod/App::Netdisco#Installation. Stop after the step
"curl -L https://cpanmin.us/ | perl - --notest --local-lib ~/perl5
App::Netdisco" step, we just want to do the base install so that all the
libraries get downloaded and are linked to your new Perl/Linux environment.
5. From the perl5.prev, take the lib/perl5/App/Netdisco folder and
lib/perl5/App/Netdisco.pm file, and replace the versions in your new
Netdisco installation.
It might just work. Otherwise you'll have to go back to step one,
there's AFAICT no other way to cleanly undo a botched apt full-upgrade.
Having a separate VM or new machine will make this a lot less stressful
if it shouldn't work out.
Cheers

Just to add to Christian's good answer, step five will copy back into place
the Perl files, but the static content (web templates, etc) might not be in
that place.
Here is the old script which used to update the demo website (before we
moved to using containers) and you can see it copies the static content
from `lib/auto/share/dist/App-Netdisco` (which is likely not the same on
your system but you might dig around and find it).
https://github.com/netdisco/netdisco2-demo/blob/master/scripts/update.sh
hope this helps, and good luck,
Oliver.
