No you can't. 

You will need to either use pg_upgrade:

or do dump/restore using some combination of:

https://www.postgresql.org/docs/16/app-pgdump.html

https://www.postgresql.org/docs/16/app-pg-dumpall.html

and

https://www.postgresql.org/docs/16/app-pgrestore.html

https://www.postgresql.org/docs/16/app-psql.html

Is that a correct analysis?  I just want to make sure.
