Freeform - Can I cut and paste Freeform boards to a new User then delete from my User account?

Until recently, my partner and I shared a common User account. We have now set up individual User accounts and activated our individual iCloud accounts. Is there a way to get the Freeform boards that my partner created in our previously common User account, cut and pasted to her own User profile so that I can then delete them from my User account (which was previously the common User account)? I know I could share via iCloud but would rather delete if possible and if I send as PDF, she will no longer be able to modify the boards. I have tried copy and pasting the Freeform Containers folder over to her User profile but the boards do not appear when she opens Freeform. Any help appreciated thanks.
