Hi there Apurv Sapar
Thanks for using QandA platform
SQL Server Enterprise Edition is licensed per 2-core pack, and the current price is around US$15,000+ (exact cost depends on region, reseller, and whether you include Software Assurance). To upgrade from Standard to Enterprise, you don’t need a fresh install — just run the SQL Server Installation Center → Maintenance → Edition Upgrade, enter your Enterprise key, select the instance, and complete the wizard. SQL Server services will restart, so plan for brief downtime. After upgrade, you can confirm with SELECT SERVERPROPERTY('Edition')
If this helps kindly accept the answer thanks much..
