I'm currently using an old Lenovo laptop as a headless Ubuntu 24.04 server, running several services like Pi-hole, Jellyfin, and SAMBA with USB HDDs mounted via UUID. Recently, I've been experiencing freezing issues, although the hardware specifications—8GB RAM, 20GB swap file, and a 4-core processor—seem to be sufficient since the load averages around 1.8 with only 2GB of RAM in use. I've checked logs but haven't found anything indicating the cause of the freezes. I'm considering switching to another laptop and want to know if I can just transfer the hard drive and connect the USB HDDs without encountering problems. Will Ubuntu adapt automatically?

Transferring the hard drive to a new system might require you to recreate the UEFI boot entry. Once you boot into the new system, you may also need to adjust the Netplan configuration to match the new network adapter name, which usually changes. Make sure you're prepared for that! If you're familiar with modifying Netplan, that should be straightforward.
When you move your USB HDDs, they should operate like regular USB drives. Just keep in mind that if you don't see them pop up, you might need to mount them manually or update your fstab file. As for transferring the hard drive, it should work since your UUIDs are correctly set up in fstab. To troubleshoot the freezing, have you tried running smartctl on your disks or a memtest? Checking the services via journalctl could help too.
