How do you migrate Legacy CIS data in to SAP IS-U CCS?

At a high level these are the two important types of master data that needs to be migrated from legacy CIS into SAP CCS. They are:

1. Business Master Data - Business Partner, Contract Accounts, Contracts.



2. Technical Master Data - Connection Object, Connection, Premise, Installation, POD and Device Location.

In addition to the above two types of master data, there are several other types of application & customizing data related to Billing (Rates, Rate Types, Rate Categories, Prices, etc), Work Management (Notifications, Orders, etc), Materials Management, Plant Maintenance and Quality Management modules that will need to be brought in before SAP CCS go-live. For the sake of this discussion, we will limit ourselves to the above two types of master data.

Migrating legacy CIS data into SAP acceptable format will need a careful analysis by an organization wide cross-functional team that is responsible for management of this data. These are some of the following factors you will need to keep in mind:

1. Is there duplication of data in Legacy CIS, which can be consolidated in to the NEW SAP CCS system?



2. Does the SAP number range for master data need to be same as in Legacy CIS system?



3. What tools are to be used for data migration - EMIGALL, LSMW, ABAP?



4. Validating and building input files to feed it into one of the above tools and getting it in to SAP.



5. Validating the SAP data loads and consistency.
