I'm trying to use dtutil to automate the migration of hundreds of packages from SQL Server 2016 to SQL Server 2019 in another server.
It seems dtutil is unable to find the project/package folder.
All I found in docs and links seems to refer to msdb, but here, the folder/project/package data is stored in SSISDB database tables instead.
Based on the official documentation:
The dtutil command prompt utility is used to manage SQL Server Integration Services packages. The utility can copy, move, delete, or verify the existence of a package. These actions can be performed on any SSIS package that is stored in one of three locations: a Microsoft SQL Server database, the SSIS Package Store, and the file system.
There are several alternatives to migrate SSIS projects from SSISDB to another instance such as backup and restoring the SSISDB database, using a third-party solution, or using the Package import wizard.
You can refer to the following articles for more information:
