We want to upgrade our dual stack ECC6 Netweaver 7.0 to dual stack ECC6 Netweaver 7.3 and then split the stack later when we want to upgrade to Netweaver 7.4. Documentation is very confusing saying we need to split before the upgrade because 7.3 does not support dual-stack split and 7.0 releases are the only ones to support dual-stack. Other more recent documentation says that 7.3 now supports dual-stack split and that now 7.3 is the last version to support dual-stack. Which is right?
Can we upgrade our dual stack ECC6 Netweaver 7.0 to dual stack ECC6 Netweaver 7.3 and then split the stack later?
We are starting the upgrade so we need an answer to this fast.
Yes, You can upgrade dual stack from NW 7.0 to 7.3, better do dual stack split and then perform the NW 7.3 upgrade. Kindly refer the SAP upgrade guide. Could you share the your current stack support pack level? and kernel release & level ?
NW 7.4 will not support dual stack on ECC system.
