SUM "Stack configuration not useable" - NW 7.4 Upgrade


we are facing following Problem: While upgradeing of our SLD (Netweaver PI 7.1 Dual-Stack) to Netweaver 7.4 Dual-Stack with SUM check:


Last error code set: Stack configuration not useable: The stack configuration is not valid for the system

I generated the stack.xml file with Mopz and it ist located in the directory with the Upgrade Packages.

I searched in various posts with the same error for example:

Error when upgrading an SRM System 5.5 to SRM 7... | SCN

But the System-Number is correct and in the xml file and in lmdb too.

The verification check in LMDB is green.

Can anybody help me ?

    Hi Lukas,

    Generate the stack for the system again.

    I think , your XML file has got corrupted or you are using a wrong stack.xml file.

    With Regards
