[06:02:47.057] ERROR (#1): MigrateDevDbLegacySourceError: Source database '<evidence>/pre-v2.sqlite' holds 1 legacy threads the server has not imported into V2 yet, which this command cannot carry over. Start a server once on a T3 home holding a copy of it so it imports them, then pass the userdata/statev2.sqlite that server leaves behind as --source.
