pg_upgrade can do that if you use link mode (pg_upgrade -k). It is
strongly recommended to make a snapshot of the data directory before the
upgrade, so that you can roll back to the original if things go wrong.
Going up only to 9.6 means that you will be pressed to move to a more
recent version soon, since 9.6 goes out of support at the end of the
year. Why not go straight to, say, 12?
I suggest to add more storage space.
The pgsql-es-ayuda@lists.postgresql.org can help you if you would like
to discuss in Spanish.
