We need to upgrade Magento web store from ver. 220.127.116.11 to Magento CE 18.104.22.168 (most recent). Store address: [url removed, login to view] (remove -). It is new website with few products, there were no custom code modifications. The only modified part is theme. There is one extension that will need to be installed.
It will need to be moved to another hosting account. New hosting account is on VPS.
The project is relatively simple but must be done in professional manner.
Thanks for your time.
