Migration from FileStorage to sharing-grdb

[yliu342]

Hi, it was very exciting to see this new lib sharing-grdb that can have your SharedState backed by GRDB. I've got an app that has been using the old ShareState, is there any guideline to how I can migrate from using FileStorage to this new lib?

We don't have an article written for this (though we could), but we did demonstrate a technique in this episode. The idea is to insert the data from the file storage into the database when you migrate the DB, and then delete the data from the file storage. Here's the code from the episode:

Great thank you. I will add a step in migration to insert the filestorage record into the db.
