Where is the answer of Ratna i can't see, does anyone have any concrete solution/approach for the same?

Hi Veera,Please share your experience whether you were able to upgrade hybris 6.3, because I have to also do the same kind of upgradation that is from hybris 5.4 to hybris 6.3 version but adobe is not providing support beyond hybris version 5.7.What is the approach you followed?Thanks,Ashish
