That document is damaged and can’t be opened. But you think it’s got versions saved, if only you could get at them. How?
Three workthroughs considering options and issues in migrating to a new Mac, with info on late migration, macOS upgrading, and Thunderbolt adaptors.
Don’t just throw it in a box and send it off: what happens if its internal storage is replaced or wiped? What about protecting sensitive files? Does a T2 chip make this difficult?
More work to be done before your migration is fully complete: check your workflows, key security settings, disk health, licensing, backups.

Adds support for local snapshot statistics, Dark Mode, fixes a bug, and is now notarized for your added security.
Detailed comparison of how Time Machine backs up HFS+ and APFS volumes, including its use of local snapshots, with diagrams.
When Time Machine backs up an APFS volume, it works quite differently from the way it did on HFS+. Explored here using log entries from Mojave.
Practical tips for those intending to upgrade early, from checking compatibility, preparing workarounds, to making a copy of the installer.
