I was responsible of the migration project, which i leaded through 3 majors steps :
Project preparation:
Based on my experience, migration preparation is the major step, especially on the business process reengineering, because this will really guarantee a smooth execution and confirm the business value.
Upgrade and migration execution:
This is mainly basis operations which consist of a hardware/OS/DB switch from the current underlying SAP CRM database to SAP HANA, combined with the CRM application upgrade. Take care that only unicode SAP systems can run on HANA.
You have to consider all the systems in your landscape, each can have a particular role to play in the migration to ensure a smooth execution on the productive system.
Basically, development system can be copied, migrated and adjusted in order to keep your (source) development system up for productive system correction. Corrections and business processes improvement (plus optional productive system correction during elapsed time) will have to be reported following the landscape migration routes.
Quality system can be used to optimize your productive system downtime by knowing which smart split will have to be done during data export, especially if your QA system reflects well your productive data. (FYI, SAP can provide specific service to totally avoid productive system downtime if needed).
Standard tables comes already defined in-row or in-column stored. Consider to may have adjustement to do only on specific objects.
All custom programs compiled correctly, we only made some small adjustments regarding ABAP development guidelines for SAP HANA (have a look to thomas.jung/blog/2012/02/23/developers-journal-first-steps-into-the-sap-hana-world).
Follow up activities:
In the final step of the customer project, we had to concretely establish the business process reworks and improvements identified during preparation phase. Regarding the follow-up upgrade and migration, some basis operations have to be done after the productive system migration which are well described on the below links.
This step is really the most exciting for the team as you have all the tools in hands to unlock the power of SAP HANA. Clearly, performance on data access changes the game: the main point is that you can involve very much more data at each process steps that you did previously. So from daily business operation and operational reporting to high level reporting and strategic plan, you can really see the business value by going deeper into your analysis or by aggregates steps that you had previously to carry on a splited way.
CRM business orders can be monitored deeply, performances are boosted for all kind of research, reports and calculation, records and exchanges are speed up within the orders, actions & follow-up copies. Even time reduction on batches processing can be reduced and even avoided because they are already processed during transactional time. SAP CRM 7.12 brings it’s own set of new functionality especially leveraging big data capabilities, where SAP HANA is really outstanding.
I recommend you take a look at this CRM on HANA overview https://cookbook.experiencesaphana.com/crm - it is a very well comprehensive and simple description of the project which business user and technical team can refer to. And of course the well-known SAP Service marketplace for upgrade
and migration purposes https://service.sap.com/upgrade-crm and https://service.sap.com/osdbmigration.
All the best for your CRM!
