Change "many" to "one" in relation


I’ve seen that from one to many it is supported (CHANGELOG: Apr 27 / My Space (official), Convert to-one relation field → to-many relation field)

What would be the way to change from “many” to “one” ?

I have setup by mistake a few weeks ago a relation from Solution “Big Solution” to itself (Versions), and I’d like to change so that a Version has only one “Big Solution”.

The field direction is locked :

Is there any workaround ?


There’s no way to change an existing relation in that direction, but you can create a new relation and copy paste from table view I suppose.
Or you can write an automation that copies over the entities.
