Upgrades do not require on-site access.
Every production system should have a backup; so I keep a second server
on standby. For upgrades; I upgrade the backup system; test my apps on
the upgraded system; then with only a few minutes downtime I resync the
data and make backup hardware productions server. Then I upgrade the
original system; test it and migrate back again.
This process tests the disaster recovery process with every upgrade.
This process only requires on-site visit when upgrading the OS; never
packages like Postgresql.
