If we need to import orders from a live magento site onto a development site for example if a client already has a magento website in use and we need to overwrite it with the new webcarepreview version, we should import all up to date orders before overwriting.

You can install an extension that lets you export and import orders...

If you cant import all of the orders it will probably be because you have created test orders in the webcarepreview site and they will have the same order ID as some of the orders on the live site. You can use this plugin to remove any test orders before importing the live orders..
