an upgrade to sierra
the mac takes a hike
Upgraded Mac Mini running Mac OS X 10.10.5 Yosemite directly upgraded to macOS 10.12.4 Sierra.
Mixed clients Mac OS X 10.7.5 Lion to macOS 10.12.4 Sierra and some legacy SMB devices. Except for a hostname/DNS changes that needed to be corrected, it went smoothly.
