In SQL Server Integration Services (SSIS), the version number indicates the specific release and update level of the software. Knowing the version number is important for several reasons. It helps in identifying the features and capabilities available in the installed version, determining compatibility with other components, and resolving any technical issues or bugs specific to a particular version.
There are multiple ways to check the version of SSIS installed on a system. One common method is through the SQL Server Management Studio (SSMS) user interface. By connecting to the Integration Services catalog and expanding the “Integration Services Catalogs” node, you can find the version information under the “Properties” section of the SSISDB database.
