Magento 1.9 - What is the best way to edit core files???

[james_green101]

I need to edit -> app/design/adminhtml/default/default/template/sales/order/view/items.phtml, editing core files is dangerous, may i know how can i edit without affect core files.

eg: Some case we can edit the file app\design\frontend\default\theme327k\template instead of edit core path app\design\frontend\base\default\template. Same how to follow in app/design/adminhtml?

Hello,

mostly admin part developer doing into core files, if you want to do theme-based then you need to create child theme using below URL and you need to do it
