S/4 HANA Conversion Road Map

Hi,

Below is the Road Map to migrate from ECC to S/4 HANA.

SAP Solution Manager 7.2 Updates

Dear Consultants,

Below are the few new points in Solution Manager 7.2 Compare to 7.1

1. SolMan 7.2 will not support dual stack, it is now individual ABAP & JAVA stacks.

2. We need to install Both the instances Separately.

3. The SID of Both the instances is different.

4. Java will not have any UME, so while installing JAVA stack we need to provide the UME as SolMan ABAP.

5. J2ee_Admin & J2ee_Guest will be created while installing ABAP Stack in ABAP system.

6. SLD resided in JAVA stack.

7. SMSY transaction no more in 7.2. it will be routed to LMDB.

8. SOLMAN_SETUP is having new tabs for configuration

9. SOLMAN_WORKCENTER required Fiori setup. Content and tabs in this T-CODE have been changed as Fiori Tiles.

10. SOLAR_PROJECT_ADMIN will not work in 7.2

11. No Project Concept in 7.2

12. No Logical system assignments, new Logical grouping concept for Landscapes.

13. From Solution Manager 7.2 SP5 onwards, it is mandatory to use HANA DB or TREX to display process diagrams in Best Practice Packages.

Will be adding More.....

Suite on HANA Sizing

Hi,

There are two way's to move to Suite on HANA Environment.
1. New Green Field Implementation.
2. Migration from Traditional database to HANA.

1. New Implementation:
For a New implementation, we will do Sizing using Quick Sizer Tool (HANA).
Link for quick Sizer: https://websmp102.sap-ag.de/sizing
Go to above link and select Quick Sizer HANA Version

2.Migration from the Traditional database to HANA.
For a Migration, we will do sizing using a report provided by SAP.
Sizing Suite on HANA: SAP NOTE: 1793345 & 1872170, 1514966
Sizing BW on HANA: SAP NOTE: 1637145

Sap Note 1872170 will have report, we need to apply this note in SAP system and need to run the report to estimate the sizing of Memory(RAM) and storage(Hard drive size).
Recommended to run this report when there is less users in the system. This report may cause performance issues if we run in business hours.
