I am planning a major overhaul of a well established domain (60 Moz DA). Aside from a platform change, content reduction/consolidation and branding update, the structure of the site will be drastically changed. To me, even with redirects, this in itself is a major SEO strain on the site. I anticipate 6 months recovery time before everything is back to normal.
Would it make sense to do the conversion to https at the same time or should I do it in phases?
