Having the exact error messgaes would be really helpful.  You're sure
that you are using the pg_upgrade from 9.6?  Note that to perform a
pg_upgrade you have to have the binaries for *both* versions installed
on to the system and then pg_upgrade will perform a copy of the data
files or will create hard-links between the old and new data
directories.

Thanks!
