I am moving companies website from old installation 1.7.1 to fresh installation of Magento 1.9.3. I have moved now all the Product and Customer data easily - how do I export/import orders?
I have tried several extensions but they take huge amount of time to export/import as I have over 100k orders, so ideally I would need magento friendly way to move them.
Here is a nice extension: Bulk Import + Export Orders to CSV
I will update this post when I find something decent for Dataflow profiles.
