Convert Local to Hybrid in MSB Console

I have several backups to local repositories. I want to convert them to Hybrid backups. When I view a plan and click “edit”, then expand the “Backup Storage” section, there is an option for “Hybrid Backup”, but I cannot choose that. What must I do to convert these plans to Hybrid?

This functionality is not yet available for all plans. You can create a new hybrid plan with the same data set as a workaround.
