Please refer to the following documentation:

http://www.postgresql.org/docs/9.4/static/pgupgrade.html

CAVEAT EMPTOR: It is always advisable to have a valid pg_dump/backup before
proceeding with pg_upgrade.
pg_upgrade is faster than a reload, but in the event of unexplained
problems, a backup is always good to have as a last resort.
Also, practice upgrading in a development environment before attempting to
do so in production.
