Magento order id Increment

I had a problem that when i insert old order in to my new magento site it showing in the admin but when new order come then order id make some problem. like i had 185 order which order id was 100000421 and when new order comes then order id become 100000024.
That was a problem to me. then i go to the database find the table "eav_entity_store" and change increment_last_id in to 100000422. after doing that new order come with order id 100000422.

If you’re working with Magento Commerce you’ll most likely want to remove index.php from the URL when you go live

go to :
1) System
2) Configuration
3) Web:
secure:
Use secure URL Frontend: YES

4) edit:
http://mysite.com/.htaccess
