Hey everyone,

That is why I built HostShift, an Apache-2.0 licensed Go CLI for discovering, planning, migrating, and verifying Ubuntu and Debian servers.

The rule I would not compromise on

The source server must remain read-only.

HostShift does not install packages, stop services, enable maintenance mode, create temporary archives, or change configuration on the source. It reads approved facts and streams data directly to the target. Any target mutation requires an explicit CLI apply command.
