Error Upgrading Magento 1.3 to 1.7

Question

One of my clients asked me to upgrade his website which was built on Magento 1.3, now I am trying to upgrade it to Magento 1.4 so that I can upgrade it to Magento 1.7.

Magento Connect is not working here. So I am using SSH but when I try to initialize pear through this command:

./pear mage-setup

it throws the error:

Could not open the file /path/pearmage.php

Without initializing pear i can not proceed.

Please help, Thanks in advance

Considering that you will need to move your theme as well it would be better to point a new version of Magento 1.7 at your old database and run the upgrade.

After that you will want to move each module over and test, many won't work

Finally you will have to think about how you want to do your theme. There was no BASE folder in 1.3 so you will want to make your new theme off the current base version.

Typically we will diff the files from the old theme to see how much we can re-use, but more likely you will want to use re-do your theme using all the new layout and design files from Magento 1.7
