Hi Team,

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
>


Regards,
Sameer Malve
