Upgrading from 1.3 to newest version

Hi:



I am looking for the easiest possible way to upgrade from 1.3 to newest version. I am worried that there may be some issues with the upgrade and we cannot afford to have nay downtime. We need to upgrade to fix the bug issues.



I tried to download all files and database and configure it locally on an linux Ubuntu machine but did not have any luck getting the site to load.



I want to make sure I am covered with the old site / files just in case something goes wrong.



Any suggestions would be greatly appreciated.



Thanks

Install a 2nd copy of your shop at another or subdomain or just a directory.



Upgrade that shop.



When you're satisfied copy the new shop to the main location.
