Hi @chatofai
there is no quick or “easy” way to migrate the data from one project to another. If your free index isn’t too full I would just run the original embedding creation again. A similar issue is discussed here:
Also it is good practice to save the ids created (if you can) into a separate database or file just in case you need to do some operation on all of them at once.
eg. I once had to update one metadata field of all my vectors. If I didn’t have my ids there would be little I could do.
Hope this helps
