Things to remember
While it is impossible to condense every detail in this topic into a short summary, we will
try to remind you of a few of the most important things to remember.
1.
The DMO process relieves the need to perform Unicode conversions, BW up-
grades, and database migrations as separate steps. This reduces the total downtime
for the migration project and results in a more controlled and less risky migration
project.
2.
The DMO process has been developed and tested in the world's largest BW migra-
tion projects. The process is complex, but thoroughly vetted. With the details and
references included in this handbook, you have the tools you need to understand
and complete the complex tasks which make up the SAP BW on HANA migration.
3.
There are numerous hardware configurations available for deploying SAP BW on
HANA. When you require vendors to compete with each other, your company will
win. Make sure you solicit bids from numerous vendors and let those vendors
know with whom they are competing.
4.
Proper planning and preparation prevent poor performance. Whether your task is
picking your hardware, cleaning up your existing implementation, planning for
your project, or completing migrations in multi-tiered environments, you need to
be methodical and detailed in your approach to every step of the process. The keys
to a successful DMO migration include careful and thorough planning, as well as
meticulous attention to detail while applying the methods included in this hand-
book.
5.
If you have not done so already, you must complete the Unicode conversion and
security conversion as part of your migration project. BW 7.4 requires both
Unicode and security conversions, and the benefits of the simplified LSA++ archi-
tecture combined with the speed of the HANA database engine will more than off-
set the costs of migrating to SAP BW 7.4 on HANA.
6.
Since every company implements its SAP system differently, there is no cookie-
cutter approach that can cover every possible contingency. You need to apply what
you have learned in this handbook, while understanding that your migration project
will most likely vary in some details. Choose experienced partners to help you in
your implementation. There is no need to reinvent the wheel.
