Major upgrades require testing and if you're jumping from 9.2 to 12, then
you're skipping ahead 7 major releases... so it will be a large undertaking
to validate your application, but you should start ASAP so you can move to
an environment that's secure.  If PostgreSQL is that old then I suspect your
OS is also quite old, and won't have fixes for major things like Heartbleed,
etc.

If you're unsure on how to build new servers and then migrate the data, then
this is something I would suggest you need to hire a consultant to help
with.  In either case, this isn't a PostgreSQL bug so let's close this
thread, and if you want to post into a different forum then choose something
like pgsql-admin or pgsql-general:
