Other system has higher release than XI syst. in landscape

[Former Member]

Hi,

We are running an XI 3.0/NW04 system and we're currently planning to upgrade our BW 3.5/NW04 system to BI 7.0/NW04s.

In the Master for NW04s you can read the following :

"For PI, it is a prerequisite that no other system in your system landscape has a higher release than the PI system. If you want to upgrade or install an application in your system landscape, you first have to make sure that the current release of the PI system is on the same release level ‒ if required, you have to upgrade the PI system first to the new or a higher release."

After having read this, my understanding is that we have to upgrade our XI system before upgrading the BW system.

What are the consequences/implications running a system landscape where a system has a higher release than the XI-system ?

Thanks in advance for help and hints.

Rgds,

Hi Christian,

The implications are, PI as the highest release is the only supported combination. It is possible that other combinations may work, but they are not tested by SAP and, in the case of any issues, SAP Support will tell you to upgrade your PI system to the highest release.

Best Regards,

Matt
