I am in the process of Upgrading my Store from 1.8.1 to 1.9.1.
While I can upgrade to 1.9.1, the process along with testing might take about a week. As this is all done in a Staging Environment,
How can I sync the Orders, Customer, Product/Stock Updates etc. that happen in the Production server which is at 1.8.1. ?
Appreciate your time and Help.
