Description

The validation will be made ONLY on on SQL Server 2008 or higher using the 'sys.dm_db_persisted_sku_features' dmv.

  • Enterprise
  • Developer
  • Evaluation
  • Standard
  • Express

Take into account the new features introduced on SQL Server 2016 SP1 for all versions. More information at https://blogs.msdn.microsoft.com/sqlreleaseservices/sql-server-2016-service-pack-1-sp1-released/

Example: 2
PS C:\> Test-DbaMigrationConstraint -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred

used for sqlcluster.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

Alias
Required False
Pipeline false
Default Value False
