Update project mirroring ssh host key

How to update the ssh host key linked to a mirror repository ?

Following the bitbucket.org ssh host key change
we have some pull mirroring which are not working anymore.

I was wondering what is the recommended way to update the mirroring settings ?
Where is this host key stored in gitlab ?
Can I replace it, maybe with some rails console commands ?

Thanks for any advice

The easiest approach is to recreate the mirroring config.
