Thanks for catching that. Typo on my end.
Now I am getting this.
Performing Consistency Checks on Old Live Server
------------------------------------------------
Checking cluster versions ok
old and new pg_controldata WAL segment sizes are invalid or do not match
Failure, exiting
I found the setting in the current version of the instance via "show all" as
"wal_segment_size | 16MB". I guess my new instance
should be "16MB" as well when running this "initdb --wal-segsize=16 -D
/hostname/pg/NewInstance/data"?

No, you can't use the same directory to hold old and new versions at the same
time. After you're done with the upgrade, you could move the new data
directory to be where the old one had been.
