Unfortunately i'm working with a very old version of Magento (1.4.1.0) and i need to transfer the customers from this version to the newest version of Magento (1.9.10.) via CSV.
What is the best way to go about doing this?
Could i simply:
System > Import/Export > Profiles > Export Customers > Run Profile, grab the CSV and Import into the new version of Magento?
Or should i apply some edits to the CSV first, so the new version of Magento can read it correctly?
