Can't delete snapshots: "must not have dependent clones"

Hello all, i have some snapshots took 2 months ago by the system itself.
I want to get rid of them, but i can’t delete them cause Truenas says they have dependent clones.

i’m assuming they were taken when migrating from core to scale…
how to do?
Thanks

Yes, the iX-applications dataset was cloned to provide a safe migration from dragonfish to electric eel… I assume that was the path you took.

We’'ll be deleting it by fangtooth… anything earlier is possible, but is not documented and has risk for downgrades.

i tried this solution and seems to work:

zfs promote SSD/ix-apps/app_mounts/syncthing/config
zfs destroy SSD/ix-apps/app_mounts/syncthing/config

also with app running, so seems to be safe.
tried to stop/start the app and nothing gone wrong.

i think i will do it for all snapshots
