Reformatting data in a database
I am not sure if you have posted a video on this topic or not, but I'd love a video detailing how to migrate existing data within a database. I've come across a couple of tutorials that talk about writing migrations to change data or re-format data in a database but I'm still a bit fuzzy on the topic.
Have any examples of data migration you'd like to see? I can think of taking a table and splitting it into multiple or consolidating multiple into one table or something.
