Migrating from a brand new build on a Pi Zero 2W to a Pi 5

OS Help

First, thanks to everyone involved in this project. It's amazing.

This week I ordered an Aursinc SR-FRS and connected it to a Pi Zero 2W and configured ASL3 appliance mode using the latest 3.0.18 image. It's working great. I turned on EchoLink. I have that same choppy inbound audio issue I've seen recently reported but it does work. I then setup a KD5FMU time and weather cron job. Next I setup AllScan and finally I setup DVSwitch for DMR. It's all working perfectly.

The purpose for this test build was to set up a multi-protocol way for the Arizona Parks on the Air members and guests to join our weekly NET. Not only do we not have full coverage for repeaters across the state but we have a lot of snowbirds who head to cooler climates in our blazing hot summer. This leaves many folks left out and the thought was to bring in a way for folks to join in easily. I've done some tests with members joining from AllStar, EchoLink and DMR using our new TGIF AZ POTA Talk group. All good. Now, I want to make sure the Pi I use can scale to having up to 20+ folks attending across these various digital modes so I've ordered a Pi 5 4GB.

So now the question. Has anyone using bookworm that's all up to date with ASL3 appliance successfully moved from an earlier Pi model like I have to a Pi 5? Could you just do a Micro SD card move? Did you have to edit any boot/kernel parameters? Once you got it up and running are there any configuration file changes to optimize its functionality. I ask this as I'd seen a reference to an optimization around USB when you install on a Pi 5 and I didn't know if that gets auto detected during a migration or boot or if there is something or things that need to be manually edited to gain these optimizations.

Thanks so much for what is probably a noob questions but I did search the forum and on the net. Most google search replies said a MicroSD card swap should work find since I'm on a new version of Bookworm that is supported by a Pi 5 but I wanted to get more feedback since there may be application dependencies to consider.

Thanks in advance for the help!

In theory you should be able to just move the SD cards. The bootloader for a Pi 5 should be the correct kernel and start the system. There's no harm in trying - nothing will be damaged. I've never moved from a Zero 2W but I have moved from 3s and 4s to a 5 and it's worked fine every time.

Thank you! Pi 5 arrives today. I’ll post success or failure!

Thanks again!

I'm happy to report that I was able to just move the MicroSD card from a Pi Zero 2W to the Pi 5 and it booted and ran without issue.
Since I had used a 8GB Micro SD card on the Pi Zero but wanted something a bit larger for logs and maybe other things loaded I used Win32DiskImager to create an IMG file of the 8GB working MicroSD card and save that on my PC. I then used it to copy the IMG to a pair of 64GB Micro SD cards. As I booted and tested each I used Raspi-Config/Advanced/Expand Filesystem to use the entire 64GB. Also, my SimpleUSB.conf had a specific USB device listed that than just an equal sign for auto discovery so I used the asl-find-sound command to get the correct USB port identifier and update the devstr = with the correct number. Everything is working perfectly.

Thanks again for the assist!
