Is it possible to run both drupal 6 and drupal 7 on local MAMP server?

I have a drupal 6 multisite setup on my local MAMP server. I don't want to upgrade these sites to drupal 7 as some of the modules have not been converted to drupal 7 yet. I would also like to start using drupal 7 on the MAMP server for new开发者_Go百科 sites. However, I can't find a way to configure it so that both versions of drupal can run a multisite setup side by side (without interfering with each other).

Anyone done this with success? Any help appreciated...

Pure drupal multisite need to run the same drupal version.

You can still have your D6 in, for exemple, www/drupal6/ and your D7 in www/drupal7/, that will work.

Here is a caution, but I have not yet figured out the root of the issue (my searching for it led me to this question!). I had OpenAtrium (Drupal6) and Drupal 7 running successfully side-by-side as described above on a dev machine (separate directories, separate databases, separate etc/host domains, etc). In trying to work through an OpenAtrium image-upload issue (Clean URLs is a must), somehow, one of the admin buttons I clicked in OpenAtrium (I believe it was the OA option to repair permissions) completely trashed my Drupal 7 site. Since this was all dev/experimental, no data was lost, but be forewarned that bad things might happen.
