When performing partial migrations it is important to be aware that some data is dependent on others. For example, while it is possible to migrate a Product this data will not be complete unless the brands, categories, variations etc have been migrated. If data integrity is important then rather use the complete migration option instead.
The list of known data migration issues can be found here.
