<para>A rolling upgrade from 0.96.x to 0.98.x works. The two versions are not binary compatible.</para>
<para>Additional steps are required to take advantage of some of the new features of 0.98.x, including cell visibility
labels, cell ACLs, and transparent server side encryption. See the
<xref linkend="security" /> chapter of this guide for more information. Significant performance improvements include a change to the write
ahead log threading model that provides higher transaction throughput under
high load, reverse scanners, MapReduce over snapshot files, and striped
compaction.</para>
<para>Clients and servers can run with 0.98.x and 0.96.x versions. However, applications may need to be recompiled due to changes in the Java API.</para>

A rolling upgrade from 0.94.x directly to 0.98.x does not work. The upgrade path follows the same procedures as <xref linkend="upgrade0.96" />. Additional steps are required to use some of the new features of 0.98.x. See <xref linkend="upgrade0.98" /> for an abbreviated list of these features.
