I'm looking for an ETL solution that we can create a configure by hand and then deploy to run autonomously. This is basic transformation, it need not be feature heavy. Key points would be free or open source'ed software that could be tailored more to suit specific needs.
In fact, this could be reduced to a simple DB migration tool that will run on a Linux server. Essentially the same as the above but we probably won't need to validate / transform the data at all besides renaming columns.
I forgot to mention that this is going to have to be very cross platform. I'd like to be able to deploy it to a server, as well as test it on OSX and Windows.
