Upgrading from the Previous Release

The following information describes how to upgrade your API Manager server from the previous release, which is APIM 1.7.0. To upgrade from a version older than 1.7.0, start from the doc that was released immediately after your current release and upgrade incrementally.

Migration scripts' location is https://svn.wso2.org/repos/wso2/carbon/platform/branches/turing/products/apimgt/1.8.0/modules/distribution/resources/migration-1.7.0_to_1.8.0.

Upgrading the product databases

1. Download the API Manager 1.8.0 from http://wso2.com/products/api-manager.  
2. Stop all running API Manager server instances.
   
3. Back up the databases of your API Manager 1.7.0 server instance.
   
4. Download the migration scripts from the migration script location and execute the database upgrade scripts on your old database. You must select the script corresponding to your database type. For example, if your database is MySQL, execute migration-1.7.0_to_1.8.0/mysql.sql on it. The script adds all the schema changes done to API Manager tables in the 1.8.0 release.

Migrating the configurations

In this section, you move all existing API Manager configurations from the current environment to the new one.

1. Open <APIM_1.8.0_HOME>/repository/conf/datasources/master-datasources.xml file and provide the datasource configurations for the following databases. You can copy the configurations from the same file in the API Manager 1.7.0 instance.

   • User Store
   • Registry database
   • API Manager Databases

2. Edit the registry configurations in the <APIM_HOME>/repository/config/registry.xml file and the user database in the <APIM_HOME>/repository/conf/user-mgt.xml file.

3. Move all your synapse configurations by copying and replacing <APIM_1.7.0_HOME>/repository/deployment/server/synapse-config/default directory to <APIM_1.8.0_HOME>/repository/deployment/server/synapse-config/default directory.

   If you changed the default URLs in AuthorizeAPI.xml and TokenAPI.xml files, do not replace them when copying. They are application-specific APIs.
   

Upgrading APIM 1.7.0 to 1.8.0

1. Start the API Manager 1.8.0 and log in to its management console.

2. To re-index the artifacts in the registry, perform the two steps given below.

   a) Rename the lastAccessTimeLocation in the <APIM_1.8.0_HOME>/repository/conf/registry.xml file.

   E.g.,: Change /_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime to /_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime_1

   b) Shutdown AM 1.8.0 and backup and delete the <APIM_1.8.0_HOME>/solr directory and restart the server.

3. Copy the contents from your previous <APIM_HOME>/repository/tenants directory to the same directory in the API Manager 1.8.0. Do not replace the _TokenAPI_.xml, _RevokeAPI_.xml and _AuthorizeAPI_.xml files in the /default/api sub directory.
4. Download and build org.wso2.carbon.apimgt.migration.zip as a JAR file.
5. Place the JAR file in the <APIM_1.8.0_HOME>/repository/components/dropins folder.
6. Start the server with the -Dmigrate=1.7 command to run the 1.7.0 to 1.8.0 swagger and doc resource migrations.

   Upgrading external stores

7. If you have external stores configured in the registry, follow the steps below:

   1. Log in to APIM 1.8.0 management console and click the Resources -> Browse menu.

   2. Load the /_system/governance/apimgt/externalstores/external-api-stores.xml resource in the registry browser UI, configure your external stores and save.

   Upgrading Google analytics

8. If you have Google Analytics configured in the registry, follow the steps below:

   1. Log in to APIM 1.8.0 management console and go to Resources -> Browse menu.

   2. Load the /_system/governance/apimgt/statistics/ga-config.xml resource in the registry browser UI, configure the Google analytics and save.

   Upgrading workflows

9. If you have Workflows configured in the registry, follow the steps below:

   1. Log in to APIM 1.8.0 management console and go to Resources -> Browse menu.

   2. Load the /_system/governance/apimgt/applicationdata/workflow-extensions.xml resource in the registry browser UI, configure your workflows and save.
