I am migrating an existing D6 site to D7. The D6 installed module list includes 102 enabled contrib modules (although the required modules are probably considerably less). Using the "Download & Extend" tool on Drupal.org, I began searching for corresponding D7 versions of the site's D6 enabled modules, but am having a difficult time making a 1:1 correspondence between the enabled D6 and available D7 modules based on deprecation, name changes, and inclusion in core.
Is there a better way to identify the available Drupal 7 contrib modules I may need in this upgrade? Thanks.
