Once you have RewriteRules, you must find any rules using mod_alias (Redirect by that name) and translate them to mod_rewrite (RewriteRule with [R] flag). This is easy to do.
We keep telling you to put a blank line after each RewriteRule. But the opposite is important too: don't leave blank lines between a RewriteCond (or group of RewriteConds) and the RewriteRule it belongs to.
Empty lines have no syntactic meaning in htaccess. (They do in robots.txt.) They are purely for your own benefit, to help you stay organized and remember what goes with what.
