How to leaves old link - routing?

[eluser]devastator[/eluser]
I use this redirect

RewriteRule ^article.php?id=(.*)$ /article/index/$1 [L]

but not work
changing config file also don't work

My site have 10 000 uniques per day 90% of them are form google that articles are in first-five positions. I want to not change the urls because google will reindexing me 2-3 months and visits will be more more lower.

I try everything that i know and think will work. Please help me to hardcode that.
