I have an old (512MB) Pi 2B thats running Buster with no problems except
that the SD card is now 16GB rather than the original 4GB. Its always
been run headless, though I've never tried using wifi with it.

The difference may be that I've always done in-situ upgrades by editing
/etc/apt/sources.list and /etc/apt/sources.list.d/raspi.list to
successively change the version name: wheezy->jessie->stretch->buster
in these files, and then:
- making sure the old distro is fully up the date
- running "sudo apt-get update"
- "sudo apt-get -y dist-upgrade"
- rebooting into the new version

I handled resizing the SD card by:
- using 'parted' to create and format the partitions on the new card
- using dd to copy each partition from the old to the new card.

The boot partition must be FAT32 and the filing system should be ext4.

I've migrated the system to a bigger SD card twice. The boot partition
stayed at its original size from 'wheesy' to 'stretch', but this wasn't
large enough for 'buster' now that the kernel modules needed by Pi 2, Pi
3 and Pi 4 are all part of the same distro, so I increased it to 1GB for
'buster'.

I've always used the rest of the SD card for the ext4 filing system.

HTH: all these upgrades and SD card migrations have 'just worked' for me.
