This page takes you through the general steps for upgrading product versions based on Carbon 4.3.0 to Carbon 4.4.0.

...

  1. Copy the data from the old database to the staging database you created. This becomes the new database for your new version of Carbon.
  2. Download Carbon 4.4.0 and connect it to your staging database. 

  3. Update the configuration files in Carbon 4.4.0 according to the requirements.

    titleConfiguration changes from Note these configurations that were introduced in Carbon 4.3.0 onwards:

    Given below is a list of configurations that were new from Carbon 4.3.0 onwards. Therefore, if you are in the process of upgrading to Carbon 4.4.0 from Carbon 4.2.0, be mindful of these configuration changes:

    Configuration File 
    axis2.xml file stored in the <PRODUCT_HOME>/repository/conf/axis2/ directory.The following new parameter is added: <parameter name="httpContentNegotiation">true</parameter>. When this is set to 'true' , the server will determine the contentType of responses to requests, by using the 'Accept header' of the request.
    tenant-axis2.xml stored in the <PRODUCT_HOME>/repository/conf/tomcat/ directory.The default value for the "httpContentNegotiation" parameter is set to 'true': <parameter name="httpContentNegotiation">true</parameter>.
    catalina-server.xml file stored in the <PRODUCT_HOME>/repository/conf/tomcat/ directory.

    Keystore parameters are added under the <Connector> element as shown below. This setting allows you to use separate keystore and security certificates to certify SSL connections. Note that the location and password of the default "wso2carbon.jks" keystore is given for these parameters by default.

    Code Block
    keystoreFile=location of the keystore file
    keystorePass=password for the keystore 
    master-datasources.xml file stored in the <PRODUCT_HOME>/repository/conf/datasources/ directory.Default auto-commit setting for a data source is set to false: <defaultAutoCommit>false</defaultAutoCommit>.
    carbon.xml file stored in the <PRODUCT_HOME>/repository/conf/ directory. 
    1. New parameters to define proxy context path as shown below;

      Code Block
      <MgtProxyContextPath></MgtProxyContextPath>
      <ProxyContextPath></ProxyContextPath>

      Proxy context path is a useful parameter to add a proxy path when a Carbon server is fronted by reverse proxy. In addition to the proxy host and proxy port this parameter allows you add a path component to external URLs. See Adding a Custom Proxy Path for details.

    2. The following port configurations have been removed:

      Code Block
      <!-- Embedded Qpid broker ports →
      <EmbeddedQpid>
      <!-- Broker TCP Port →
      <BrokerPort>5672</BrokerPort>
      <!-- SSL Port →
      <BrokerSSLPort>8672</BrokerSSLPort>
      </EmbeddedQpid>
    3. In Carbon 4.2.0, the following registry keystore configuration was required for configuring the keystore keys that certify encrypting/decrypting meta data to the registry. From Carbon 4.3.0 onwards the primary keystore configuration shown below will be used for this purpose as well. Therefore, it is not necessary to use a separate registry keystore configuration for encrypting/decrypting meta data to the registry. Read more about keystore configurations in Carbon 4.4.0.

      Code Block
      <RegistryKeyStore>
                  <!-- Keystore file location-->
                  <Location>${carbon.home}/repository/resources/security/wso2carbon.jks</Location>
                  <!-- Keystore type (JKS/PKCS12 etc.)-->
                  <Type>JKS</Type>
                  <!-- Keystore password-->
                  <Password>wso2carbon</Password>
                  <!-- Private Key alias-->
                  <KeyAlias>wso2carbon</KeyAlias>
                  <!-- Private Key password-->
                  <KeyPassword>wso2carbon</KeyPassword>
      </RegistryKeyStore>
    registry.xml file stored in the <PRODUCT_HOME>/repository/conf/ directory.The default value changed to 'false' for the following setting: <versionResourcesOnChange>false</versionResourcesOnChange>.
  4. Copy the following directories from the old database to the staging database.
    1. To migrate the super tenant settings, copy the <PRODUCT_HOME>/repository/deployment/server directory.
    2. If multitenancy is used, copy the <PRODUCT_HOME>/repository/tenants directory.
    Note

    Note that configurations should not be copied directly between servers. 

  5. Start the server.
