You will create a new data directory for 10 and the data from 9.5 will get moved to that new folder after the upgrade. The metadata info in the catalog will get updated accordingly to pg10.
At the end of the upgrade, the 9.5 folder can be dropped after making sure everything is working. This script is also get generated by pg_upgrade.

Hi Debraj,
You can use pg_upgrade utility from Postgresql. This works with inplace option. Look at this link below for more details.
This option is also be the fastest for upgrading from 9.5 to PG10
