Re: Experiment
Can't help but feel they'll be a tad busy trying to convert 25yrs worth of kludges and 'business critical' processes into an entirely new platform.
True that, but the end result depends on the contractor. There are good ones, who can manage it, overshadowed however by the mass of the usual suspects, like Accidenture, who are prone to send - and bill - a legion of newbies to upskill themseleves by breaking things and learn from the wreckages.
And S/4HANA is not entirely a new platform, ECC code base is still there, mostly used - including the Utilities industry solution. It depends on how the custom development was made (modifications or not), and how the integration to non-SAP applications was done (since some older technologies might have been deprecated).
