Hi Bec

I just completely altered my site, similar to what you are planning. I went with 301 redirects, in the htaccess, as G does accept those. I am in the process of removing them, rather than leaving them in place. G does not like meta refresh pages, but seems okay with 301 redirects.

Your site already being listed, I'd not use a new domain. Too many risks with G, so while it would be easier to just use a new domain, keep the old, and build the new pages as you go, so as to keep the indexed pages alive in G.

my 2 cents :morning:
