Stack file for upgrade to Solution manager 7.1
we have a problem to upgrade to Solman 7.1.
Our system is a Solution Manager 7.0 EHP1 Stack 26
For the upgrade you need to create a stack file in the MOPZ.
When we want to create an upgrade XML with SAP Solution Manager maintenance optimizer , it is only possibel to create a file for a stack package. We can not choose upgrade to 7.1 ???
Can anyone help?
