upgrade my website Magento from version 1 to version 2
Hi I am going to upgrade my website Magento from version 1 to version 2 in few days. I would need the php version 7.2 for that. But before going live and shutting down the currecn website which is run on php 5.6, I would like to test everything on php 7.2. What are my option of doing this? My plan includes 6 websties. Is it possible if I create a new website, it will be running on php 7.2, while the old website will keep running on php 5.6.? I need to make sure the current website is not affected.
