But the artifacts and my dataset of my old experiments still use the old adress for the download ( is there a way to change that ) ?

MotionlessCoral18 the old artifacts are stored with direct links, hence the issue, as SweetBadger76 noted you might be able to replace the links directly inside the backend databases

i have found some threads that deal with your issue, and propose interesting solutions. Can you have a look at this ?

Hi MotionlessCoral18
Have these threads been useful to solve your issue ? Do you still need some support ? 🙂

Yes, so far i came back to the old adress 🙂

Hi MotionlessCoral18
You need to run some scripts when migrating, to update your old experiments. I am going to try to find you soem examples
