rman diskgroup compatibility issue?

Hi,

I have a source database on oracle EE 12.1 RAC using asm (grid infra is 12.2). Compatible is set as this:

DATA                       sector_size        512                      N

DATA                       logical_sector_siz 512                      N

DATA                       content.type       data                     N

DATA                       compatible.asm     12.2.0.1.0               N

DATA                       compatible.rdbms   12.1.0.2                 N

DATA                       compatible.advm    12.2.0.1                 N

The database I want to migrate is 12.1.0.2.0

I want to migrate it to a new system oracle EE 12.2 RAC. Oracle 12.1 and 12.2 are installed. Grid infra is 12.2.

DATASLOW                   sector_size        512                      N

DATASLOW                   logical_sector_siz 512                      N

DATASLOW                   content.type       data                     N

DATASLOW                   compatible.asm     12.2.0.1.0               N

DATASLOW                   compatible.rdbms   11.2.0.0.0               N

DATASLOW                   compatible.advm    12.2.0.1.0               N

-- set oracle home to 12.1.0.2
