Migrating from the Neo Environment to the Multi-Cloud Foundation

How to guide
Access the SAP Help Portal to read about the details on migration.

Environment (runtime)
SAP BTP supports multiple environments:
- Cloud Foundry (CF)
- Kyma
- Serverless
- ABAP
Cloud Foundry Environment
Because of the polyglot nature of the Cloud Foundry environment, you're also free to choose your own approach. You're not forced to use one language exclusively, but can choose between Java, Node.js, and many more.
| NEO Environment | CF Buildpacks | Description |
|---|---|---|
| Java | Java | The SAP Java buildpack is a Cloud Foundry buildpack for running JVM-based applications. The buildpack provides the following runtimes: Tomcat, TomEE, TomEE 7, and Java Main. |
| Java | Node.js | SAP BTP uses the standard Node.js buildpack provided by Cloud Foundry to deploy Node.js applications. |
Database
| NEO | CF |
|---|---|
| SAP HANA | SAP HANA service for SAP BTP |
| SAP ASE | SAP ASE service |
Scenario Components
Migrating a scenario from the Neo environment to the multi-cloud foundation implies migrating all components involved:
| NEO | CF | Guide |
|---|---|---|
| SAP IAS | SAP IAS | No migrations neccessary, but for costs reason maybe switch to SAP Customer Data Cloud or Microsoft Azure B2C |
| HTML5 Applications | HTML5 Application Repository Service | Standalone SaaS apps need an @sap/approuter Migrating |
| UX | UI Theme Designer | SAPUI5 Themes can be supported using the theme designer runtime |
| SAP Document Management service | SAP Document Management service vs Object Store on SAP BTP | Migration Guide |
| SAP API Management | SAP Integration Suite (incl. SAP API Management) | This is no longer available as a separate service; it is a capability within SAP Integration Suite (see rebranding guide). Migration |

Development
SAP BTP supports the SAP Cloud Application Programming Model to develop new components using Java or Node.js.
It supports a CDS driven service approach to deliver oData v4 services out-of-the-box (v2 with a proxy).
Productively supported databases are SAP HANA service for SAP BTP and SAP ASE service.
