50 groups were deleted by mistake. Please don't ask how.
So from a 2 weeks old backup, we're able to extract a CSV from civicrm_group and civicrm_group_contact
group_id, name, contact_id, email
We would like to reimport the groups and their assignation to contacts. The contacts are already in the system normally. We would not want duplicate users
Afraid of simply going to the civicrm_group_contact table and just filling it through phpmyadmin
Any tip? Thanks!
