System Information
  • Strapi Version: v3.6.8

  • Database: MongoDB

I currently have two collection type: A - B
In these two collections, I set up like this:
2 field for A:

  • Text field
  • Relation field: (OneWay type) : A has one B

2 field for B:

  • Text field
  • Relation field: (OneWay type) : B has one A

I create 3 entries for each: A1, A2. A3 and B1, B2, B3
I assign entry in these relation field: A1 → B1, A1 → B2, A1 → B3
But now I want to change the type of the relation field to Many-to-Many, I did some test that I see most of the types will cause me to lost the data (lost the entries that I has already assigned before) except Many-to-One.

So is there any way that I can change the type of the relation without losing the data that I have already assign?
