Pre-migration considerations
In this section, we discuss considerations for moving an SAP
system. Not all of these considerations apply when only moving the
central instance, as we do in this guide.
NOTE: We only discuss moving the central instance for the
application server in this guide. A migration that involves
moving the database is outside the scope of this guide.
Such a migration requires an SAP OS/DB Migration Check.
See https://service.sap.com/osdbmigration for more details.

Operating system compatibility. When introducing a new
application server into your SAP ecosystem, be sure that its
operating system is compatible with the other servers running in
the ecosystem. For Advanced Business Application Programming
(ABAP) servers, such as the ones we are dealing with in this guide,
SAP says that all UNIX versions, including Solaris, and all Linux
versions SAP supports are 100 percent compatible with each other.

Hardware differences. The SPARC processors are big-endian,
while the Intel Xeon processors are little-endian. However, Red Hat
Enterprise Linux Advanced Platform for SAP applications ships the
proper sap-locales sorting packages so you will not have any issues
with data sorting between the two systems.
NOTE: If you are running a non-unicode SAP system, make
sure to install the additional locales with adapted sort
orders. We describe how to do this in Appendix A.
Third-party application compatibility and licensing. While you
should not have any problem moving your SAP-based applications,
you should look carefully at any third-party applications you may
