Handling legacy customization in data migration  

‍

Customization of an application – that is, adapting its features to customer’s needs – is often not only desirable but actually necessary to make a solution work. Many legacy installations that have been serving customers for years have been heavily customized. Small changes add up over the years. And when requirements from several stakeholders, e. g. different departments, have to be considered, managing customizations gracefully almost becomes an art form. 

However, when the time arrives to move off of such an application, the prior benefits of such customizations can quickly turn into pitfalls for the data migration: 

· When documentation is missing, assessing the situation and defining the migration scope gets difficult. 

· When the experts that set up the system are gone, it ishard to identify, qualify and extract the data corresponding to customizations. 

· When large amounts of data became superfluous or incomplete, this may be overlooked and lead to bad data quality. 

· If references between individual data records are no longer clear, data may be lost.  

conemis software helps to overcome this problem: One pillar of its functionality is Application Assessment. This feature delivers unified analysis and scoping for immediate assessment of legacy systems from Oracle, SAP, Microsoft, Salesforce, and others. It will save time in quickly understanding applications and data – and thus relieve you from any issues that might be caused by customization.
