Any websites I have built before using Expression Engine have been from scratch.
One of my existing clients would like their site rebuilt as its 4 years old. I am planning on using another domain to copy the existing site over and upgrade it from 2.5.x to 2.7.x and then create a new design and edit a few custom fields.
The issue is, this is a high profile e-commerce site that is in 24 hour use. New members, new orders and new products are constantly being added.
If I build the new site on a copy of the site, after I finish the new design, and a few amendments to the system (perhaps a few custom field changes) I am wondering how I should go about getting the new data back into the new system.
Any advice on this matter would be greatly appreciated.
