I have a website which consists of "subsites". These subsites have their own different admin, subdomain (using purl), content and theme/homepage.

It's on drupal 6 and this is achieved using spaces, purl and organic group module.

I need to migrate this drupal 6 to 7 now..

  1. So first question: Has anyone ever migrate a site with similar configuration and modules? Is the migration smooth and "straightforward" (upgrade the modules and that's it?)? Are there issues I need to prepare myself to tackle them?
  2. Are the functions found in OG D6 version is available in OG D7 version? The site heavily makes use of og_get_group_context()

thx in advance for your feedback and replies.
