Hello I'm interested in finding out the answer to a simple question but cannot find the relevant info online. I'm wondering if it's possible to use an R/3 system with a BW/4HANA or an S/4HANA with a BW anyDB? I'm asking because we have an R/3 and a BW 7.0 system which we are planning to migrate to S/4 and BW/4 respectively. The question now is whether or not we can migrate one system at a time, and once we have one of them upgraded, connect to the old system which remains (either R/3 or BW 7.0) depending on which one we migrate first.
Thanks,
Dimitar
