Hello Andreas,
Please correct me if I'm wrong.
I checked PAM. Kernel 741_rel supports existing OS/DB(windows 2008r2).
I chose NW 740 SAP_BASIS SPS6 in MOPZ, by that I got 741 Kernel. It supports till sap_basis sps7.
The only thing is Version 740 SAP_BASIS SPS8 requires 742 Kernel. So I chose SPS 6. it's enough for our environment.
So I can continue the upgrade and It support productive environment right?
Thanks & Regards,
Venkatesh P
