Here's the situation. I want to roll out Office Web Apps to our SharePoint instance. The only trouble is that a lot of files are still in .doc format, and if you try to edit them in Office Web Apps it has to convert them first. That's OK, conversion is good, but it makes a copy of the file and adds (converted) to the filename. This is really going to throw our users so I want to avoid it if possible.
What I'd really like is to be able to run a script, go to lunch, and come back to find that every .doc has been upgraded to a .docx. The Word Automation Service is a great candidate for this. Most of the tools I've seen so far will upgrade the document but will dump the old file in a 'converted' folder somewhere.
We have a lot of documents so I'd like to avoid manual processes as much as possible. How should I approach this?
