Improve DTS to SSIS package migration with DtsToSsis-Prepare
Two weeks ago I wrote a tool to ease and improve the migration of a DTS package to a SSIS package. I named the tool DtsToSsis-Prepare, it is available with full source code at www.sqlbi.eu and now I wrote a larger article that describes the needs that DtsToSsis-Prepare try to solve.
For people who are too lazy to click a link, I extracted a part of the article in this post.
This is a DTS package before treatement: UDL connections are used to easily change connection parameters.
If we try to migrate this DTS package into an SSIS package, we obtain this result.
It is not very useful to get one SSIS package containing two DTS packages.
Using the DtsToSsis-Prepare tool with all options enabled we get this “prepared” DTS package.
As you can see, UDL connections have been converted to standard connections and have been consolidated into only two physical connections. At this point this DTS package would be less parallelized, but we will never execute this package, we just want it to migrate in a fair way to SSIS. The next picture shows the result of this migration.
We have two Data Flow Tasks corresponding to our original Transform Data Tasks.
I would be glad to receive feedback and comments about this tool: probably there are other features that would be useful to add. There is also a dedicated support forum to submit comments/bug/ideas.
