Error: System PRD is a ECC 6.0 product system!

Dear All,

I'm trying to upgrade my erp ecc 6.0 system, specifically want to upgrade the kernel to 7.01.

I'm going through the same drill...creating a MOPZ transaction.

at the step: choose stack. whatever target stack i chose, i get the error:

Error: System PRD is a ECC 6.0 product system!

i don't know what the issue is....I'm not able to move any further.

Thanks in advance!
