Migration methodologies
Here are the three generally accepted migration methodologies open to SAP customers today.
1) Brown昀椀eld: system conversion
吀栀e other side of the coin is that it can a昀昀ect the
future accuracy of your analytics. Why? Because
you’re moving toxic (uncleaned) data, much of
which you likely won’t need anyway on a dayto-day basis. Also, moving this huge volume of
unrequired data is going to turn out expensive if
you’re moving to the cloud. In short, brown昀椀eld
is an extremely complex project. Processes and
interfaces may need to be redesigned. 吀栀ere is
also limited opportunity to make major changes
rapidly and cost-e昀昀ectively. It will weigh on
your IT investments as a purely technical
project that adds no value to the business.
吀栀e Brown昀椀eld approach is a conversion of
the overall system that a company has in place
to SAP S/4HANA. For smaller companies or
recent SAP customers, this can work well. But
for large corporations, it involves taking all
historical data, documents, and processes built
up over the years across various systems and
then migrating them fully to the new destination system. 吀栀e advantage of this strategy is
that companies can theoretically be sure that all
of their information – legacy as well as active –
will be transferred to the new system.
