In talking with both customers and prospective Cloud customers my team and I still get a lot of questions regarding how to perform a Cloud migration, i.e. when to perform the ECC system upgrades, how to move/install to a new OS (if needed), steps to move to HANA, and many more questions
The SAP DMO (Database Migration Option) toolset simplifies and dramatically streamlines the entire SAP migration with one process, one tool, one downtime. DMO allows SAP users to update an existing SAP system to a higher release version and/or can migrate to SAP HANA database.
Here is a technical guide to help you get started with what you need to know about DMO » https://managecore.com/blog/your-technical-guide-sap-dmo-database-migration-option
