Downgrade ER2

Version downgrades are not supported for the Enterprise Recon Master Server as certain features, data sets, storage formats and / or components in newer versions of Enterprise Recon may not be backward compatible. Downgrading a newer version of the Master Server datastore to an earlier version of Enterprise Recon may leave the system in an undesired state.
