PotNeed for migration may arise due to MongoDB's transition to a non-free license SSPL, which is based on the AGPLv3 license but is not open, as it contains a discriminatory requirement to provide not only the code of the application itself but also the source texts of all components involved in providing cloud service under the SSPL license. <\/p>\n
