Alternatively, considering that Microsoft sometimes uses codenames for projects, perhaps SSIS 840 is a codename for an internal project or a feature set. Given that, I should proceed by assuming SSIS 840 is a newer version focusing on certain enhancements. Alternatively, maybe they meant SSIS 2022 (the version tied to SQL Server 2022) and the user used a different identifier. To avoid misinformation, I should mention that SSIS is part of SQL Server and discuss the latest available features as of SQL Server 2022, noting that version numbers can be confusing and advising checking official sources for the most current info.
