Postgres upgrade success loop due to prior postgres 8 to 10 migration

In a loop of:

To complete the upgrade, rebuild again using: ./launcher rebuild app

I must be missing something. Complete log below. Appreciate any help.

Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
./analyze_new_cluster.sh

Running this script will delete the old cluster's data files:
./delete_old_cluster.sh
-------------------------------------------------------------------------------------
UPGRADE OF POSTGRES COMPLETE

Old 10 database is stored at /shared/postgres_data_old

To complete the upgrade, rebuild again using:

./launcher rebuild app

Looks like there are some files remaining from 2 years ago since the last upgrade:

mv: cannot move '/shared/postgres_data' to '/shared/postgres_data_old/postgres_data': Directory not empty
mv: cannot move '/shared/postgres_data_new' to '/shared/postgres_data/postgres_data_new': Directory not empty

Can you move those files elsewhere before rebuilding?

That was it! Thank you, @Falco.

Thanks, added this to the FAQ. I will also add detection to this state in the upgrade script.
