...

  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.

...

  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.

    Note

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

...

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

  2. Copy the 'swagger-doc-migration' directory from the migration scripts location to <APIM_1.8.0_HOME>. The new directory path will now be <APIM_1.8.0_HOME>/swagger-doc-migration.

  3. Configure <APIM_1.8.0_HOME>/swagger-resource-migration/build.xml file with the following properties:

    PropertyDescriptionregistry

    .

    home

    Path to the APIM distribution. In a distributed setup, give the API Publisher node's path.usernameUsername for the server. For a tenant to log in, provide the tenant admin username.passwordPassword for the server. For a tenant to log in, provide the tenant admin password.hostIP of the running APIM server. In a distributed setup, give the host of the API Publisher node.portPort of the running APIM server. In a distributed setup, give the port of the APIM Publisher node.versionVersion of the server.

  4. Using the command line, go to <APIM_1.8.0_HOME>/swagger-resource-migration folder and execute ant run. If the above configuration is successful, you get a BUILD SUCCESSFUL message. It modifies the structure of Swagger content in the registry.

  5. 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.

    EgE.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.
