    Description

      If a 2.4 node with 2dsphere indexes is upgraded to 2.6/3.0, the indexes will have an implicit version 1. However, a resync of the node (or sync of a new node) will implicitly recreate the index with explicit version 2.

      This shouldn't be a big issue aside from possible (but unlikely) differences in behavior between replica set nodes. Once SERVER-13875 is fixed, sharded clusters should handle this well.
