We have a replica set with 2 members and one arbiter in production. 10gen documentation states that 2.0 to 2.2 is a binary-compatible “drop-in" upgrade and so it's 2.2 to 2.4. Is it safe to upgrade from the 2.0 version directly to the 2.4 version?
This question was posted on stackoverflow and closed as offtopic. It was suggested to me that I try to ask it here.
