This (Friday) evening I upgraded my RPi 512MB 2?B from Stretch to Buster
by following the directions on the RaspberryPi.org website for doing the
Stretch->Buster upgrade in situ. Overall it took about 5.5 hours to
complete and was fairly straight forward and fairly painless.

Niggles (there were a few):

- every 30-60 minutes the upgrade asked whether it should keep a
  modified configuration file and waited for an answer, so if you
  use this way of upgrading, keep an eye on it for these questions
  so the upgrade doesn't sit waiting for input for too long.

- at about 66% complete the upgrade stopped after consistent making
  repeated complaints about the locale not being set. I set a default
  locale and restarted the process by rerunning the same command. This
  time it ran to completion

- Removing the unwanted packages listed in the Buster upgrade
  instructions and then running the "apt autoremove" upgrade command
  again deleted the listed packages plus lot of other unneeded packages.
  A third upgrade run didn't make any more changes, so I rebooted.
  This was uneventful.

- Finally, I ran my usual weekly update script to see if it would
  find any overlooked updates. None were found but a another 300MB
  of packages were reported as unwanted on the voyage and deleted.

- A final run of the weekly upgrade showed nothing more to do.
  "df -h" showed that Buster is about 0.7 GB bigger than Stretch.

  Some other mousing around showed that Buster, unlike Stretch and
  prececessors, now runs an MTA by default. It uses Exim 4.

  My 'todo' list now includes the replacement of Exim with Postfix
  to bring it inline with my other systems.

- A final reboot worked perfectly, so I ran my usual test routine,
  a CVS update of a moderately complex multi-module C program, followed
  by a clean compile and running a regression test suite, showed that
  this sequence worked as expected.
