Netweaver 7.00 upgrade to 7.01

Hi Guru's,

I need to upgrade my NW 7.00 to 7.01 to be able to perform client copy (Source client is at ECC 6.00 PL15 running in Netweaver 7.01 PL3), import & export releases must be on the same level, for sure all of you will agree.

I tried manually using tcode SAINT to install Add-on packages but it won't allow me to proceed. It says I should use the EHPI which is already replaced by SUM.

I tried using SUM but only to update SP Stacks of ECC 6.0. and it is successful.

There's no option there to upgrade Netweaver EHPs only without including EHP for ECC 6.0

===Client Copy===

Source Client -> SAP ECC 6.0 PL 15 / Netweaver 7.01 PL 3

Target Client -> SAP ECC 6.0 PL 15 / Netweaver 7.00 PL 18

Please help me!

regards,

Maix
