+# Manually handle URL redirections when transferring from an old custom domain to the new one
+#############################################################################################
+- This will allow you to manually redirect URLs if you move systems
+- Likely not the best for performance reasons but is a workable solution
+
+################
+# Instructions #
+################
+
+1 )Get list of all links from old and new site. These commands will crawl through your sites and create links to all articles and save them to a text file
+
+	wget -nv -r old_site -o URLs_old.txt
+	wget -nv -r new_site -o URLs_new.txt
+
+2) In the output text fields, manually find the correct mappings
+
+3) Manually create PHP object of this format and save it in the 404.php file
+	$REDIRECT_URLS = [
+		"/old/url/path" => "/new-url/path",
+	];
+
+4) Style this 404 page
+
+*/
+
+$REDIRECT_URLS = [
+	"/old/path/to/page" => "/new-page-to/page",
+];
+
+$url = @$REDIRECT_URLS[$_SERVER["REQUEST_URI"]];
+if(!isset($url)) $url = @$REDIRECT_URLS[$_SERVER["REDIRECT_URL"]];
+if(isset($url)){
+	header("Location: " . $url, TRUE, 301);
