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@xxxxxxxxxxxxxxxxxxxx can help you if you would like to discuss in Spanish. -- Álvaro Herrera 39°49'30"S 73°17'W
