Does anyone know if we can archive Collaborator data and import/migrate it to GitLab(Triage-ops)?

we are currently using Collaborator but it will expire soon

so we are trying to migrate all the users data to our new tool/workflow, Triage-Ops

but im not sure if we can import Collaborator data to GitLab (Triage-Ops)

we do have XML doc, some other type of files

Please let me know if anyone knows about this
