I am working on redesigning a fairly high profile blog. I suggested the best way to do that, rather than mockups, is to just upload their wordpress export to a new WP install on domain. That way they could see how any changes reflect the blog "live". Once they are good with design, they can just upload and use the theme.
Is this recommended? Any potential issues I may be unaware of?
The other issue is this particular blog has about 500 posts but the categorization and tagging is a mess and needs to be re-done to be effective. If I did this on my side with an export, it might take a week or so. They client would then have to import the fixed export... right? Any issues with that? What would happen to the content that was created in the previous week? Would a next export have to be created and the previous weeks content be joined to the older, fixed, export?
