Template compatibility

Hello,

I use opencart version 1.5.6.3 and I want to change my template (theme). I selected a template but this is for opencart 1.5.3.1

I want to ask whant do you think, the selected template will work or not on my 1.5.6.3 version ?

it will probably not work right. But if you ONLY have THEME Files within your CUSTOM THEME SUB, and no 1.5.3.x custom files, beeing PART of your THEME, thereby replacing DEFAULT 1.5.6.5.x SOURCE FILES, then, you can just upload your Theme and find out, what works, and what wont work. You can then always remove the Custom Theme Sub again, without doing any harm to something else.
Good Luck
