Updating WSO2 API Manager
WSO2 introduces the WSO2 Update Manager (WUM), which is a command-line utility that allows you to get the latest updates that are available for a particular product release. These updates include the latest bug fixes and security fixes that are released by WSO2 after a particular product version is released. Therefore, you do not need to wait and upgrade to the next product release to get these bug fixes. For information on updating WSO2 API Manager with the latest available patches (issued by WSO2) using the WUM tool, see /wiki/spaces/updates/pages/16318501 in the WSO2 Updates Guide.
Persisting Index data
The indexing related information of WSO2 API Manager is stored in the <API-M_HOME>/solr/data
 directory. Once the data is indexed, it is stored in the index directory. Refer Add Apache Solr-Based Indexing for more information.
Before you discard the old API Manager instance,
You must take a backup of the <API-M_HOME>/repository/data
 directory and copy it to the API Manager binary pack in the <API-M_HOME>/repository/data
directory that is updated with the WUM updates.
Persisting WSO2CarbonDB
To avoid conflicts that can be occurred in the update process, it is recommended to persist the local H2 databases as well.
Before you discard the old API Manager instance,
Take a backup of <API-M_HOME>/repository/database/WSO2CARBON_DB.h2.db
and replace it to the API Manager binary pack in the <API-M_HOME>/repository/database
directory that is updated with the WUM updates.
If you are using the existing local H2 database for WSO2MetricsDB as well,
Take a backup of <API-M_HOME>/repository/database/WSO2METRICS_DB.h2.db
and replace it to the API Manager binary pack in the <API-M_HOME>/repository/database
directory that is updated with the WUM updates.
For more information on run time and configuration artefact directories of API Manager, see Common Runtime and Configuration Artifacts.
