Hi,surya kannan
When purchasing SQL Server 2022, Microsoft also provides you with the right to downgrade to SQL Server 2019 or SQL Server 2017. This downgrade is called downgrade rights and gives Microsoft users the right to use prior released versions of a particular software without having to purchase these versions.
For detailed information about the license issue, you can call 1-800-426-9400, Monday through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist. Or you can go to Volume Licensing Service Center support. Please choose region/language and choose to call or have web.
Best regards,
