ExaCC upgrade 19.7 to 19.13 RDBMS RAC+DG

Hi




My customer ExaCC - 19.7 RDBMS RAC + DG (under another exaCC)


want to upgrade RDBMS from 19.7 to 19.13


it will upgrade exaCC (where DG is secondary) and 2weeks later it upgrade primary exaCC (production site)


is it possible to have DG secondary at 19.13 and primary on 19.7 or it need to redo DG after migration. I believe it's quite difficult to switch primary to secondary during upgrade ...


for info: grid will remain on 19.7 version


regards
