Hello,The last step is definitely wrong. You should not copy postmaster.opts, postgresql.base.conf and postgresql.conf. Instead, you should configure the postgresql.conf in the PostgreSQL 10 data directory to match the parameters of your old cluster. Copying pg_hba.conf seems alright, since the one from 9.5 is compatible with 10.
Correction: since your configuration files are clearly not in the data directory, but in /etc/... you should edit them (and copy pg_hba.conf) there, not to the data directory.
Sincerely,
Alex
