We are trying to perform the Major version upgrade on RHEL 8 using RHEL-certified repo `rhel-8-for-x86_64-appstream-rpms` from PG 15.6 to PG 16.4 using `pg_upgrade` but we are facing the below issue.
As the binaries are getting upgraded in-place `/usr/bin` hence while performing pg_upgrade we are not getting the older binaries.
pg_upgrade command is as follows.
[2024-10-04 11:18:47] $ /usr/bin/pg_upgrade -b /usr/bin/ -B /usr/bin/ -d /pgData/pgsql/15/data -D /pgData/pgsql/16/data -c [2024-10-04 11:19:19] [2024-10-04 11:19:19] You must identify the directory where the old cluster binaries reside. [2024-10-04 11:19:19] Please use the -b command-line option or the PGBINOLD environment variable. [2024-10-04 11:19:19] Failure, exiting
