SAP on Azure Implementation Guide

By: Nick Morgan, Bartosz Jarkowski

Overview of this book

Cloud technologies have now reached a level where even the most critical business systems can run on them. For most organizations SAP is the key business system. If SAP is unavailable for any reason then potentially your business stops. Because of this, it is understandable that you will be concerned whether such a critical system can run in the public cloud. However, the days when you truly ran your IT system on-premises have long since gone. Most organizations have been getting rid of their own data centers and increasingly moving to co-location facilities. In this context the public cloud is nothing more than an additional virtual data center connected to your existing network. There are typically two main reasons why you may consider migrating SAP to Azure: You need to replace the infrastructure that is currently running SAP, or you want to migrate SAP to a new database. Depending on your goal SAP offers different migration paths. You can decide either to migrate the current workload to Azure as-is, or to combine it with changing the database and execute both activities as a single step. SAP on Azure Implementation Guide covers the main migration options to lead you through migrating your SAP data to Azure simply and successfully.

Heterogenous migration

Whenever there is a change to the operating system, DBMS software, or the hardware platform, the migration becomes heterogeneous. Rather than some form of relatively simple copy process, all data residing in the source database must be exported to flat files in the source environment, copied to the target environment, and then imported into the target database. This Export/Import method is more complex than backup/restore, but it offers additional capabilities, and as the basic migration tools are supplied and fully supported by SAP, this is the recommended option if you plan a platform change.

More recently, SAP has enhanced the basic Export/Import solution with a relatively new option to migrate systems to the cloud with the Database Migration Option with System Copy. It offers the same capabilities as the Classical Migration, but in addition you can perform a system upgrade or Unicode conversion in a single step.

Because the export files are much smaller...
