Abstract: Computer-implemented methods and systems for migrating business data from source business system to target business system are described. The method performed by server system includes receiving request from user device to migrate source data from source business system to target business system and accessing source metadata associated with source business system and target metadata associated with target business system. The method includes generating one or more source staging tables based on source metadata. The one or more source staging tables include information of a plurality of source columns that is to be mapped. The method includes creating mapping sets for mapping source data to the target metadata, transforming the source data stored in the one or more source staging tables into a target data structure based on the target metadata, and loading a target staging table associated with target business system based, at least in part, on the transforming step.
