Data migration from one SAP system to another SAP system due to merger.
I want to understand, what would be required for migrating data from one SAP system to another, PA, OM, Time and Payroll are to be migrated. Currently data flows between the two through ALE. The two systems have to be merged.
Which all teams will be involved, and what tools can be used.
Typically how long this activity can last.
What could be areas of concern? I can think of PY only.
Any methodology delivered by SAP to support this?
Will it be similar to any Data migration from non sap to sap, except mapping?
