Bringing in existing data to the new system adds significant value in the initial phase as it makes it a lot easier to demonstrate analysis capabilities such as charts and reports. This improves the ability to convince stakeholders such as health programs and donors to support the new system. In most cases there exists a large amount of electronically stored data from in-house database systems, excel sheets or other third party systems. This data should whenever possible be imported and mapped to the data elements and the organisational units (locations/facilities) of the new system with whatever feasible technical solution. This should be regarded as a one-time job for boot-strapping the database and does not have to turn into an elegant and reusable routine.
