MOVING TO ORACLE 12c
Restore the database as you would normally do it.

But at the end, instead of:

alter database open resetlogs;


Open the database with:

alter database open resetlogs upgrade;


Then upgrade the database to the new release. Instructions can be found at:

Manually Upgrading a Non-CDB Oracle Database

Note that the above documentation is for version 12.1.

Direct upgrade from 11.2.0.2 to 12.2 is not supported, you need an extra upgrade step to 11.2.0.3 or 11.2.0.4 or 12.1 before upgrading to 12.2.
