Management Pack Versioning to change
Per Jeanie...
Previously, I learned what management packs version numbers mean, but that will be changing in the near future. Coming soon, the part of the version number that was previously tied to the version number of Operations Manager (6.0.6278.22) will be the version number of the management pack, and the part that was the management pack version (6.0.6278.22) will be incremented for updates to the management pack.
The details page for the download and the management pack guide will establish the required version of Operations Manager.
