The kernel upgrades are completed and all NFS and NIS connections have been verified. The upgrade was relatively uneventful. Everything is back up.
I am in the process of upgrading vps3 because the version of Devuan has reached end of life and it no longer has repositories from which to receive security updates. At the conclusion of this process there will be about 1/2 hour downtime for it to image it.
The free public services https://friendica.eskimo.com/, https://hubzilla.eskimo.com/, and https://nextcloud.eskimo.com/ are back in service.
