Bartosz Ratajczyk explains why upgrading SQL Server Integration Services packages could be in your best interest:
Looking at the times of the upgrade (it takes milliseconds) we can live with automatic version migrations during thousands of executions. So – is there any gain if we retain it?
Let’s take a closer look at the SSIS Toolbox. We are migrating to SSIS 2017 from the lower version, let’s say the source is SSIS 2012. Open SQL Server Data Tools (for Visual Studio 2015 or 2017, does not matter for now) and load your project. I will use SSDT for VS 2017 with sample project created for SSIS 2012. See the SSIS Toolbox for the project in version SSIS 2012? There is a Script Task following an FTPTask.
I will upgrade the SSIS project to the latest version (and write more about it in few lines) and take a look at the SSIS Toolbox now.
Now we can see additional tasks for Hadoop. Upgrading the project does at least two things that are interesting to us: it uses the latest versions of the tasks and components, but also introduces the new elements to use.
There are some benefits, but those come with a little bit of risk.
