Others may have noticed me already pointing this out at length in
other threads. 😀
If you start with a system that was installed as i386 it's easy to
just install an amd64 kernel.
Some try to fully cross-grade userland to amd64, e.g.:
https://wiki.debian.org/CrossGradingo
Or by using this script:
https://salsa.debian.org/crossgrading-team/debian-crossgrading/-/blob/master/INSTRUCTIONS.md
However, both of those involve some very hairy steps. It's never
been fully automatic for me and has involved some outcomes that were
tricky to recover from. I wouldn't recommend that a non-expert tries
it. It took longer than just reinstalling.
I have had customers try to do this and end up taking a wrong step,
resulting in a very broken system. Repairing it for them isn't
something they pay me for so I've advised reinstall at that point
also.
So on most of these legacy systems I stopped with just the kernel,
since that's the majority of the benefit anyway.
Thanks,
Andy
