I would replicate to the new server from the old using WAL to get an up to date copy of the DB. Shutdown the new copy and run pg_upgrade. Then you can fallback to the old system if there is a problem.

Either that, or I was thinking about doing a backup of the live cluster and restore it to a test cluster. Then pg_upgrade the test cluster. Yes. It's a little bit of work and I am sure there should be a better way to g about doing this.
At least after all these, Oliver would be able to know how long it truly takes to upgrade.
