Windows – Duplicate Oracle Database from Windows to Linux

I have a regular Oracle 12c database already created, named ECLS. I've been given a pile of .BKP files, not from this database, and have been told to replace everything in ECLS with the contents of these files.

Here's how I've attempted to do that so far:

$ sqlplus / as sysdba
SQL> shutdown immediate;
SQL> startup pfile='/u01/app/oracle/product/12.1.0/db_1/dbs/initECLS.ora' nomount;
SQL> exit
$ rman auxiliary /
RMAN> duplicate database to ECLS backup location '/u01/dumpfilesgohere' NOFILENAMECHECK;

Inside the pfile, I have this line set:

*.enable_pluggable_database=true

It runs for 2.5 hours, then it fails with this error message:

The fact that I'm seeing Linux errors about files not being found and Windows file paths suggests to me that this is somehow related to the fact that the .BKP files were generated on a Windows machine while the place they're being used is a Linux machine.

How can I account for this? Is there some setting in the pfile that I need to change during startup? Or is there another argument that needs to be passed to RMAN in the duplicate command?
