What kind of information are you planning on migrating in your osCommerce mirgration tool? I realize there are probably as many configurations for osCommerce as there are installations of it. Are you planning on moving only products and categories or are you also planning on moving customers and order history?
Would there be any plans for moving multi-store installations as well. I can understand the difficulty in doing this but it seems like with your multi-store implementation it should at least be possible. I’m sure there are many people waiting on any update to this.

For the osCommerce migration tool we are planning on importing products, categories and customers. Order history is a bit more tricky so we are looking at having some archive order table to display old orders. These orders will not be editable in any way in Magento.
Coming from X-Cart, I’d say, forgot the import for now, focus on the codebase and get it stable, import tools can come later on after the fact… Surely most of us here know how to do a MySQL export/import via CSV…
