How to easily find whether the contibuted modules have been updated or not? I am trying to upgrade my project form D6 to D7. I have used several contributed modules in my porject.

I am aware that I should check availability of all the contributed modules in version 7 before starting upgrade process.

In this case I need to check every independent contributed modules seperately whether it is available or not.. 

My question is:


  Is there any other easy way to check availability of all the
  contributed modules via programatically or any other modules to do
  this... 


BTW : Not using drush...
If you are going to attempt an upgrade from D6 to D7, you really should consider using Drush.  Really strongly.  The Drush Site Upgrade command will save you a lot of time, and as a bonus, it will tell you the upgrade status of your D6 modules, and will recommend alternate modules for some modules with no upgrade path, but for which alternatives exist.

If you really don't want to use Drush, you can use the Upgrade Status module.  It also has an upgrade assist block that will help you walk through the upgrade process manually.
