Hi,
We're evaluating the possibility to upgrade very old system (R/3 4.7) and convert it to S/4HANA (most updated, like 1709 release).
We want to do it at once, with only one downtime time period. Is it possible ?
We know it is required to upgrade 4.7 to ECC6.0 (maybe EHP8) and unicode converted before conversion to S/4. And conversion requires some pre-check activity which take considerable time. I'm afraid that it is not feasible to do it together with reasonable downtime.
Anyone have done 4.7 --> S/4 project ? any suggestion ?
By the way, is there any official support service or customer care for S/4HANA conversion project ?
