Data migration is the process of moving data from one environment to a new one; it may be used to support migration from one database to another or between major upgrades of a database. The implementation of master data management may also require data migration. The data integration, ETL,ELT and replication, which are primarily concerned with moving data between existing environments, may be used in order to support the migration process .Data migration is often undertaken as a part of a broader application migration (for example: migrating from SAP to Oracle, consolidating SAP environments or migrating from one version of SAP to another. or when migrating to SaaS (software as a service) environments it is important for data migration to be automated as much as possible, especially where these applications have been acquired directly by the business rather than via IT. Data migration projects are undertaken because they support business objectives. There are costs to the business if it goes wrong or if the project is delayed, and the most important factor in ensur¬ing the success of such projects is close collaboration between the busi¬ness and IT. Whether this means that the project should be owned by the business? treated as a business project with support from IT?or wheth¬er it should be delegated to IT with the business overseeing the project is debatable, but what is clear is that it must involve close collaboration. This white paper is about the acquisition of FMG(Fast Moving Goods)business of one company(COM-1) by another company (COM-II) resulting in the merger of the FMG business of COM-I into COM-IIs. It involves migration of huge amount of data from one company to the other resulting from partial M&A between COM-I and COM-II keeping the following parameters in check -Data integrity, Time(duration of engagement),Cost of technology, Man hours sent, Downtime, Maintaining availability of application. Huge data migration is not only cumbersome but requires special tools and techniques for maintaining integrity of the data. Migration of data from one source (company) to the other (company) requires time and effort and has huge cost implications that are not visible on the surface and hence extensive design, planning and funding are needed. Various tools are evaluated for migration of data but owing to the complexity of the existing system which involves Open road as front end, tuxedo at middle tier and Oracle 10g at the backend and there were many critical business rules applied at all the three tiers, that needs to be taken into account while migrating the data. This involved lots of study and research in term of determining the best methodology for migration data from one landscape to another landscape. Please note the two landscapes may be on two entirely different platforms involving lots of complexity and contradictions. There was a need to study in details the application and hardware architecture of both the systems for the purpose of data migration /integration. For the purpose of data migration from one environment to another, all the validation (including Biz validation at front end and middleware and data referential and integrity validations at backend) should be considered and cannot be bypassed for the sake of migration.
