Question: Explain about Data Migration and Cut-over Activities in SAP
Answer:
A. Data Migration:
Data migration involves transferring the legacy data into SAP system
Those who are implementing SAP solutions, legacy data is exported into a spreadsheet format, and the LSMW generates the input file to load the data into SAP.
The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data from legacy systems into an R/3 System.
The LSM Workbench carries out the following tasks:
- Reads the transfer data from one or more files (for example, spreadsheets, sequential files etc.)
- Converts the data from the source format into the target format
B. Cut-over Activities
Cutover Activities are Master/Transaction Data uploading strategies depending upon the when we are going live. As per that, you have to give the information to your core team. If you going live at the middle you have to upload the all P&L Account items and B/S Items. If you going live at the financial year start, you have to only upload the B/S Items.
