What would be the first step in data migration?

Identifying source data is the crucial first step in data migration because it establishes a clear understanding of what data needs to be transferred to the new system. This involves assessing where the data currently resides, what type of data will be moved, and the structure of that data. By identifying the source data, organizations can also evaluate data quality, consistency, and relevancy, which are essential for ensuring a successful migration process. Without knowing the specifics of the source data, subsequent steps, such as backing up the data, determining the target format, or creating a new data model, cannot be effectively executed.

In summary, this step sets the foundation for a smooth migration by ensuring that all necessary data has been accounted for and is appropriately prepared for the transfer.
