OG Merge

The purpose of this module is to provide a simple, extensible way to merge one organic group with another.

Organic groups comes with a built-in merging mechanism that is unsatisfactory.

Here is a list of things that OG Merge does better:

• Process the merging operations via a batch operation to avoid a timeout
• Allow user's that do not have the 'administer nodes' permission to perform merges (Regular users can only merge groups which they are an admin of)
• Provide a hook (hook_og_merge()) to allow other modules to act on the merge
• Allow the perserving of group admin status for users coming from other groups
• Provide a simple form that stands out as a merge feature (OG's built-in merge is only present when attempting to delete a group)
• Prevent merged content being flagged as 'updated'
