I now have to upgrade PHP from version 5.4.45 to 5.6. and I have 2 magento sites running on it.

What compatibility problems should I expect if any?

1 Answer 1


Magento 1.7 does not support PHP 5.6

It says so on the official system requirements page

enter image description here

You can expect a Blank screen when you upgrade.

I advise you to test PHP 5.6 on a stage site first before going live.
