I have a really silly question. I have a live website that is hosted on a third party host and need to make a copy of it on my private server to be used as a staging environment. So far I have got the latest Magento 2 going on my Centos7 server after almost 2 weeks of mucking around. I am aware that I have to copy the files from the magento directory on the live server which I have and the sql database which I have done also. But here is the thing, the live webiste is using Magento 2.1.5 I think, and my version I have installed is 2.3.0. Is this going to be a problem?
Thanks in advance
