Large migrations run for hours or days, mostly copying and validating, which leaves builders with a long stretch to fill while the progress bar moves.

Some migrations take a weekend. Most of that time is copying, verifying and watching counters, with very little to decide. Playlist for Slow Migrations is for those hours: the long middle of a move, between the kickoff message and the moment the row counts match.

Use the wait well. Script the validation so you are not eyeballing it, define the rollback trigger in advance and schedule the checks instead of hovering. Then let the progress bar do its work.
