I've used this guide on dozens of Pi's running both 32 bit and 64 bit
Bullseye and have not had any problems:-

https://pimylifeup.com/raspberry-pi-os-bullseye-to-bookworm/

However, this gives you a like-for-like upgrade with all the same things
installed as before, but updated - which is how I like it.

The reason the Raspbian people don't want you do this, is they have made
some big changes to the packages and the way Bookworm is set up, and
while you could reproduce these after an in-place upgrade, it's far
easier to start from scratch with a new image.

Some of the major changes are:-

* rsyslog not installed, only journald
* Network Manager for setting up networking instead of dhdcp/wpa
* Wayland installed by default, although can revert to X11

If you are running the Lite version the last one wont be an issue.

In the end it comes down to the choice continuing to do things the way
they've been since the Pi 1, or following Raspbian's currently supported
new way.
