Upgrading 11.2 -> 12.0 on EC2

[Brian Neal]

Hello,

I’m looking for advice on doing a release upgrade of a running instance.  It looks like the normal procedure using freebsd-update requires a reboot between invocations of the install command, but after the first reboot, most of the userland is non-functional, including most importantly sshd. Is it safe to run the install commands back to back without rebooting?  Or is the only safe procedure to build a new instance from scratch for each release?

Cheers,

-Brian
