+<p>Upgrades from 1.7 to 1.8 are possible with little effort as no changes were made
at the data layer and RPC changes were made in a backwards-compatible way. The recommended
way is to stop Accumulo 1.7, perform the Accumulo upgrade to 1.8, and then start 1.8. Like

-<p>The Accumulo Monitor provides an interface for monitoring the status and health
of
-Accumulo components. The Accumulo Monitor provides a web UI for accessing this information
at
-<code class="highlighter-rouge">http://_monitorhost_:9995/</code>.</p>
+<p>Existing configuration files from 1.7 should be compared against the examples provided
in 1.8. The 1.7 configuration files should all function with 1.8 code, but you will likely
want to include changes found in the 1.8.0 release notes and these release notes for 1.8.1.</p>
 
-<p>Things highlighted in yellow may be in need of attention.
-If anything is highlighted in red on the monitor page, it is something that definitely needs
attention.</p>
+<p>For upgrades from prior to 1.7, follow the upgrade instructions to 1.7 first.</p>
 
-<p>The Overview page contains some summary information about the Accumulo instance,
including the version, instance name, and instance ID.
-There is a table labeled Accumulo Master with current status, a table listing the active
Zookeeper servers, and graphs displaying various metrics over time.
-These include ingest and scan performance and other useful measurements.</p>
+<h2 id="upgrading-from-17x-to-17y">Upgrading from 1.7.x to 1.7.y</h2>
 
-<p>The Master Server, Tablet Servers, and Tables pages display metrics grouped in different
ways (e.g. by tablet server or by table).
-Metrics typically include number of entries (key/value pairs), ingest and query rates.
-The number of running scans, major and minor compactions are in the form <em>number_running</em>
(<em>number_queued</em>).
-Another important metric is hold time, which is the amount of time a tablet has been waiting
but unable to flush its memory in a minor compaction.</p>
+<p>The recommended way to upgrade from a prior 1.7.x release is to stop Accumulo, upgrade
to 1.7.y and then start 1.7.y.</p>
 
-<p>The Server Activity page graphically displays tablet server status, with each server
represented as a circle or square.
-Different metrics may be assigned to the nodes’ color and speed of oscillation.
-The Overall Avg metric is only used on the Server Activity page, and represents the average
of all the other metrics (after normalization).
-Similarly, the Overall Max metric picks the metric with the maximum normalized value.</p>
+<p>When upgrading, there is a known issue if the upgrade fails due to outstanding <a
href="https://accumulo.apache.org/1.7/accumulo_user_manual.html#_fault_tolerant_executor_fate">FATE</a>
operations, see <a href="https://issues.apache.org/jira/browse/ACCUMULO-4496">ACCUMULO-4496</a>
The work around if this situation is encountered:</p>
 
-<p>The Garbage Collector page displays a list of garbage collection cycles, the number
of files found of each type (including deletion candidates in use and files actually deleted),
and the length of the deletion cycle.
-The Traces page displays data for recent traces performed (see the following section for
information on <a href="/docs/2.0/administration/tracing">tracing</a>).
-The Recent Logs page displays warning and error logs forwarded to the monitor from all Accumulo
processes.
-Also, the XML and JSON links provide metrics in XML and JSON formats, respectively.</p>
+<ul>
+  <li>Start tservers</li>
+  <li>Start shell</li>
+  <li>Run <code class="highlighter-rouge">fate print</code> to list all</li>
+  <li>If completed, just delete with <code class="highlighter-rouge">fate delete</code></li>
+  <li>Start masters once there are no more fate operations</li>
+</ul>
 
-<p>The Accumulo monitor does a best-effort to not display any sensitive information
to users; however,
-the monitor is intended to be a tool used with care. It is not a production-grade webservice.
It is
-a good idea to whitelist access to the monitor via an authentication proxy or firewall. It
-is strongly recommended that the Monitor is not exposed to any publicly-accessible networks.</p>
+<p>If any of the FATE operations are not complete, you should rollback the upgrade
and troubleshoot completing them with your prior version. When performing an upgrade between
major versions, the upgrade is one-way, therefore it is important that you do not have any
outstanding FATE operations before starting the upgrade.</p>

+<p>Upgrades from 1.6 to 1.7 are possible with little effort as no changes were made

+<p>After upgrading to 1.7.0, users will notice the addition of a replication table
in the accumulo namespace. This table is created and put offline to avoid any additional maintenance
if the data-center replication feature is not in use.</p>
 
-<p>If the Accumulo conf directory has been configured (in particular the <code class="highlighter-rouge">accumulo-env.sh</code>
file must be set up), the 
-<code class="highlighter-rouge">accumulo-util gen-monitor-cert</code> command
can be used to create the keystore and truststore files with random passwords. The command
-will print out the properties that need to be added to the <code class="highlighter-rouge">accumulo-site.xml</code>
file. The stores can also be generated manually with the
-Java <code class="highlighter-rouge">keytool</code> command, whose usage can
be seen in the <code class="highlighter-rouge">accumulo-util</code> script.</p>
+<p>Existing configuration files from 1.6 should be compared against the examples provided
in 1.7. The 1.6 configuration files should all function with 1.7 code, but you will likely
want to include a new file (hadoop-metrics2-accumulo.properties) to enable the new metrics
subsystem. Read the section on Hadoop Metrics2 in the Administration chapter of the Accumulo
User Manual.</p>
 
-<p>If desired, the SSL ciphers allowed for connections can be controlled via the following
properties in <code class="highlighter-rouge">accumulo-site.xml</code>:</p>
+<p>For each of the other new features, new configuration properties exist to support
the feature. Refer to the added sections in the User Manual for the feature for information
on how to properly configure and use the new functionality.</p>

+<p>The recovery tool will rewrite the 1.4 write ahead logs into a format that 1.6 can

-<p>Hadoop Metrics2 is a library which allows for routing of metrics generated by registered
MetricsSources to
-configured MetricsSinks. Examples of sinks that are implemented by Hadoop include file-based
logging, Graphite and Ganglia.
-All metric sources are exposed via JMX when using Metrics2.</p>

-<p>Metrics2 is configured by examining the classpath for a file that matches <code
class="highlighter-rouge">hadoop-metrics2*.properties</code>. The Accumulo tarball

-contains an example <code class="highlighter-rouge">hadoop-metrics2-accumulo.properties</code>
file in <code class="highlighter-rouge">conf/templates</code> which can be copied
to <code class="highlighter-rouge">conf/</code> to place
-on classpath. This file is used to enable file, Graphite or Ganglia sinks (some minimal configuration
required for Graphite
-and Ganglia). Because the Hadoop configuration is also on the Accumulo classpath, be sure
that you do not have multiple
-Metrics2 configuration files. It is recommended to consolidate metrics in a single properties
file in a central location to
-remove ambiguity. The contents of <code class="highlighter-rouge">hadoop-metrics2-accumulo.properties</code>
can be added to a central <code class="highlighter-rouge">hadoop-metrics2.properties</code>
-in <code class="highlighter-rouge">$HADOOP_CONF_DIR</code>.</p>
+<p>Note that the LocalWALRecovery tool does not delete the local files. Once you confirm
that 1.6 is successfully running, you should delete these files on the local filesystem.</p>
 
-<p>As a note for configuring the file sink, the provided path should be absolute. A
relative path or file name will be created relative
-to the directory in which the Accumulo process was started. External tools, such as logrotate,
can be used to prevent these files
-from growing without bound.</p>
+<h2 id="upgrading-from-14-to-15">Upgrading from 1.4 to 1.5</h2>
 
-<p>Each server process should have log messages from the Metrics2 library about the
sinks that were created. Be sure to check
-the Accumulo processes log files when debugging missing metrics output.</p>
+<p>This happens automatically the first time Accumulo 1.5 is started.</p>
