I've a old site : site1.com but I want to move it to a folder in another site: site2.com.So site1.com/about.htm content should be accessible as site2.com/new/about.htm.Beyond doing a 301/302 I think I'd need to add content of robots.txt from site1.com into site2.com's.Similarly site1.com sitemap URLs would need to be changed and should appear below site2.com's.Is there a checklist for doing such migration?
