I am looking for some ideas on how to write user stories for a data modelling project. Our team is working on creating a new data model (staging and target) and once it is ready, data will be imported from existing database to this new model.
I am trying to split large chunks of works like creating staging data model to smaller user stories, need advice on how this can be achieved.
Ask your Developers to answer this question. They are the ones that will be doing the work and would best know how to create meaningful Product Backlog Items of such a size that they could be completed in a single Sprint.
