Certificate for Candidates

Hi, We are trying to migrate our existing LMS to OpenEdx.
We will be migrating our courses and their contents to OpenEdx. We have the data of the users who have received certificates for their respective courses. We want to migrate certificates also to OpenEdx.
Hence we would like to give certificates to those users on the course that we have created on OpenEdx.
We don’t want to migrate their progress but only the certificates.
We are new to OpenEdx, hence any guidance or support or any other alternative solutions or suggestions will be helpful.
