change fast recovery area location, no impact to existing backup

The database RCATT's FRA was set to /rman001/oradata/fast_recovery_area/, now I want to change to another directory, i.e. /dbfra/wiadb01d. Wondering if the recovery catalog still knows it.

The answer is no impact based on my below test.

The old FRA location

RMAN> list backup;

using target database control file instead of recovery catalog
