I'm currently looking into possibly upgrading our 2.0.1.1 to the latest version 3.0.3.2
I've a lot of concerns about breaking the theme ( was custom built I believe - i've inherited maintenance of this site)
I'm comfortable with html and css, but know very little php. I've been looking at how to edit twig template files.
However, on the twig documentation, it states that 'Twig needs at least php 7.0.0 to run'
On my test install of the new shop, the min php requirement was for PHP 5.4 or higher - I have 5.6
Am i going to need php7 to rebuild the theme?
Or do .tpl files still work (as long as the .tpl and .twig aren't mixed - think I remember reading this somewhere)
Scared to progress with the update if I break our shop and can't repair it
