h1. What needs to be migrated? {anchor:id=ADM.Migration.What_needs_to_be_migrated}

There are many changes between eXo Platform 3.0 and eXo Platform 3.5, including data type structure (JCR node type), pre-defined data, templates and gadgets:

* Social data: model, and space templates.
* Knowledge data: data of Forums, Wiki and Answers.
* Collaboration data: data of Calendar.
* Content data structure: Document's vote, favorite, illustration, templates, pre-defined scripts and queries.
* Platform navigation.
* Content Re-import/Migration. At the first time when eXo Platform 3.0 was deployed, the XML contents file in webapps were imported into database. During the eXo Platform 3.0 runtime, the content might be updated/deleted. Now, there are the same content in eXo Platform 3.5 webapps, so you can re-import/override the old one of eXo Platform 3.0 by new one from the eXo Platform 3.5's XML content file.
* Many Gadgets.
* Users directories structure in JCR data.

All of changes above will be migrated automatically by the migration tools that are detailed as below.

h1. Migrate with transparent configuration {anchor:id=ADM.Migration.Migrate_Transparent_Configuration}

{note}
This section discusses how to migrate eXo Platform with only one server start-up.
Every configuration will be put in 2 files: 
* With Tomcat bundle, they are in _$PLATFORM\_TOMCAT\_HOME/gatein/conf/configuration.properties_ and _$PLATFORM\_TOMCAT\_HOME/gatein/conf/portal/portal/configuration.xml_
* With Jboss bundle, they are in _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.properties_ and _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/portal/portal/configuration.xml_

*1.* Back up the eXo Platform 3.0 and its data.

*2.* Configure eXo Platform 3.5 to run with the eXo Platform 3.0 data as follows:

*i.* With Tomcat bundle, copy 2 folders "index" and "value" from _$PLATFORM\_TOMCAT\_HOME/gatein/data/jcr_ to _$PLATFORM\_TOMCAT\_HOME/gatein/data/jcr_. With Jboss bundle, copy 2 folders "index" and "value" from _$PLATFORM\_JBOSS\_HOME/gatein/jcr_ to _$PLATFORM\_JBOSS\_HOME/server/default/data/gatein/jcr_.

*ii.* With Tomcat bundle, configure the database connections in the _$PLATFORM\_TOMCAT\_HOME/conf/server.xml_ file to point to the eXo Platform 3.0 database.

For example, if your eXo Platform 3.0 runs on mySQL database, you need to configure the _server.xml_ file as below:

{code}
<!-- eXo JCR Datasource for portal -->
	<Resource name="exo-jcr_portal" auth="Container" type="javax.sql.DataSource"
		maxActive="128" maxIdle="32" maxWait="10000"
		testWhileIdle="true" timeBetweenEvictionRunsMillis="30000" validationQuery="SELECT 1"
		username="${db.username}" password="${db.password}" driverClassName="com.mysql.jdbc.Driver"
			url="jdbc:mysql://${db.host}:${db.port}/${db.jcr.name}"/>

<!-- eXo IDM Datasource for portal -->
	<Resource name="exo-idm_portal" auth="Container" type="javax.sql.DataSource"
	   maxActive="128" maxIdle="32" maxWait="10000"
	   testWhileIdle="true" timeBetweenEvictionRunsMillis="30000" validationQuery="SELECT 1"
	   username="${db.username}" password="${db.password}" driverClassName="com.mysql.jdbc.Driver"
			url="jdbc:mysql://${db.host}:${db.port}/${db.idm.name}"/>
{code}

With Jboss bundle, configure the _$PLATFORM\_JBOSS\_HOME/server/default/deploy/gatein-ds.xml_ file.

{code:xml}
    <!-- eXo IDM for portal -->
    <no-tx-datasource>
      <jndi-name>exo-idm_portal</jndi-name>
      <connection-url>jdbc:mysql://_$host_:3306/_$dbname-idm_</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>_$username_</user-name>
      <password>_$password_</password>
      <min-pool-size>5</min-pool-size>
      <max-pool-size>20</max-pool-size>
      <idle-timeout-minutes>0</idle-timeout-minutes>
      <prepared-statement-cache-size>32</prepared-statement-cache-size>
   </no-tx-datasource>
 
   <!-- eXo JCR Datasource for portal -->
   <no-tx-datasource>
      <jndi-name>exo-jcr_portal</jndi-name>
      <connection-url>jdbc:mysql://_$host_:3306/_$dbname-jcr_</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>_$username_</user-name>
      <password>_$password_</password>
      <min-pool-size>5</min-pool-size>
      <max-pool-size>20</max-pool-size>
      <idle-timeout-minutes>0</idle-timeout-minutes>
      <prepared-statement-cache-size>32</prepared-statement-cache-size>
   </no-tx-datasource>
{code}

*iii.* Delete the _JCR\_CONFIG_ table in the JCR database: "jdbc\:mysql\://${{{ {db.host} }}}:${{{ {db.port} }}}/${{{ {db.jcr.name} }}}"

*3.* Increase the JCR session time-out and JVM Xmx if you have a lot of data in eXo Platform 3.0. For example, in your current eXo Platform 3.0, there are about 200 users, 2 Gigabytes in the _gatein/data/jcr/values_ folder, and 1 Gigabyte in the _mySQL_ data, you will need to:

*i.* Configure the _$PLATFORM\_TOMCAT\_HOME/gatein/conf/configuration.properties_ or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.properties_ file by adding the following configuration.

{code}
gatein.jcr.transaction.timeout=10000
{code}

*ii.* Update JAVA\_OPTS Xmx: with Tomcat bundle, in _$PLATFORM\_TOMCAT\_HOME/bin/setenv.sh_ or .bat file, update JVM Xmx to 4G. With Jboss bundle, update JAVA\_OPTS Xmx in the _$PLATFORM\_JBOSS\_HOME/bin/run.conf_ file.

*1.* Stop server and remove the migration configurations through the following sub-steps:

*i.* Disable all migration plugins in the _$PLATFORM\_TOMCAT\_HOME/gatein/conf/configuration.properties_ file (or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.properties_):

{code}

{code}

*ii.* Delete configurations that were added before the migration in _$PLATFORM\_TOMCAT\_HOME/gatein/conf/portal/portal/configuration.xml_ or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.xml_ file.

If you do not run the JCR user directories structure migration, you need to keep the _$PLATFORM-3.5-TOMCAT\_HOME/gatein/conf/portal/portal/configuration.xml_ or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.xml_ file with the content as below:

*2.* Restart the server again. The migration process is done.

h1. Upgrade plugins details {anchor:id=ADM.Migration.Upgrade_plugins_details}

{note}
eXo Platform 3.5's Upgrade Framework is used to migrate existing data from eXo Platform 3.0 to 3.5.
{note}

A plugin is a _.jar_ file which is used for performing a specific task, especially for modifying the old data so that they are matched or compatible with the new structure. 

Plugins can be enabled/disabled via _$PLATFORM-3.5-TOMCAT\_HOME/gatein/conf/configuration.properties_. Meanwhile some of them are mandatory and must be always enabled; the others are optional and can be disabled. Also, plugins should also be disabled if you do not use certain features, such as Collaboration, Knowledge, Social, in your project.

To enable or disable a plugin, set the "enable" properties to "true" or "false" respectively, for example:

{code}
commons.upgrade.UpgradeVotingNodeTypePlugin.enable=true
{code}

When not specified, the plugins will be enabled by default.

This section shows a list of eXo Platform 3.5 upgrade plugins.

h2. Mandatory plugins {anchor:id=ADM.Migration.Upgrade_plugins_details.List_plugins.Mandatory_plugins}

These following plugins are required for upgrading to eXo Platform 3.5's new data structure, templates, skin and services.

JCR user directory structure
</emphasis>
</citetitle>
</para>

This plugin is built-in in JCR that provides an option for migrating old JCR users directory structure to new JCR users directory structure. This allows you to improve performance when having a lot of users in database.

For example, the table below shows the difference in response time of eXo Platform 3.5 (new user directory structure) against eXo Platform 3.0 (old user directory structure) while performing some actions:

|| Number of users || Type Account & Login || Load Intranet Welcome Page || Load /portal/rest/jcr/repository/collaboration/Users || Load User Private JCR Folder ||
| 500 | 13.61% | \-20.83% | \-30.12% | 14.29% |
| 1000 | 8.82% | \-25.00% | \-86.06% | 8.96% |
| 2000 | 0.20% | \-29.63% | \-93.89% | \-1.37% |
| 5000 | \-4.30% | \-33.93% | \-95.45% | \-10.67% |

Formula: (_Platform 3.5 value_ - _Platform 3.0 value_) * 100 / _Platform 3.0 value_ (negative value means better).

It can be seen that with a larger number of users, the new user directory structure performs faster than the old one, especially when accessing the user directory directly.

To enable the migration, set these 2 flags in the _$PLATFORM\_TOMCAT\_HOME/gatein/conf/configuration.properties_ file (or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.properties_) as below:

{code}
use-old-user-distribution=false
run-jcr-user-directories-migrate=true
{code}

JCR user directory structure migration will take much time, so you need to increase the JCR session time-out.
Measure the amount of data in your current eXo Platform 3.0 and use a right session time-out. For example, if there are 1000 users in current eXo Platform 3.0, you should set configuration in the _$PLATFORM\_TOMCAT\_HOME/gatein/conf/configuration.properties_ (or _$PLATFORM\_JBOSS\_HOME/server/default/conf/gatein/configuration.properties_) file as below:

{code}
gatein.jcr.transaction.timeout=10000
{code}

The time you need to migrate the JCR user directories structure depends on the amount of eXo Platform user data and your system speed.
This migration also consumes memory, so you need to make sure to have enough resource on your server and configure enough memory to update the Xmx Java option (in the _$PLATFORM\_TOMCAT\_HOME/bin/setenv.sh or $PLATFORM\_JBOSS\_HOME/bin/run.conf_ file) before running.
For example, you can use 6 Gigabyte RAM to migrate 5000 users.
