Hi,
Converting Relationship
To convert a master-detail relationship to a lookup relationship, we have to make sure there are no roll-up summary fields on the master object. If there are rollup summary fields we have to delete those fields to convert it. Deleted Roll-up fields should also be permanently deleted. This can only be done in Salesforce Classic since ‘Deleted Fields’ does not appear in Lightning.To convert lookup to the master-detail relationship you need to give parent records on all child records. Then only you can convert a lookup relationship to a master-detail relationship if the lookup field in all the records contains a value.
