This page walks you through the process of upgrading to WSO2 Enterprise Integrator (WSO2 EI) 6.5.0 from WSO2 Business Process Server (WSO2 BPS) 3.6.0.
Before you begin, note the following:
- If you are upgrading from a version older than WSO2 BPS 3.6.0, you should first upgrade to WSO2 BPS 3.6.0 and then upgrade to WSO2 EI 6.5.0.
- For information on what is new in this release and why you should upgrade, see About this Release.
- See Default ports of WSO2 Products for more information on ports. The default ports in WSO2 EI are listed under Enterprise Integrator.
The distribution folder structure has changed from WSO2 BPS 3.6.0 to WSO2 EI 6.5.0.Comparing Folder Structures: WSO2 BPS 3.6.0 and WSO2 EI 6.5.0
Business Process Server 3.6.0 Enterprise Integrator 6.5.0
See the following topics for instructions:
Preparing to upgrade
The following prerequisites must be completed before upgrading:
- Create a backup of the databases in your WSO2 BPS 3.6.0 instance.
- Copy the
<BPS_HOME>directory to back up the product configurations.
- Download the product installer from here, and install WSO2 EI 6.5.0.
Let's call the installation location of your product the <EI_HOME> directory. This is located in a place specific to your OS as shown below:
OS Home directory Mac OS
The downtime is limited to the time taken for switching databases in the production environment.
Upgrading the databases
In WSO2 EI 6.5.0, you can use the same Carbon database and BPEL/BPMN databases that you used for WSO2 BPS 3.6.0. However, you need to apply Security Advisory (WSO2-2017-0345) before connecting the databases to WSO2 EI 6.5.0.
Due to Security Advisory (WSO2-2017-0345), WSO2 EI 6.5.0 uses OAEP for data encryption in addition to the RSA algorithm (which is used in WSO2 BPS 3.6.0). This applies only to internally-encrypted data in the BPS server. Therefore, the internally-encrypted data in your current databases (such as datasource configurations, user store configurations, keystore registry entries, service security policies, event publisher configurations, event receiver configurations, and event sink configurations) should be re-encrypted using OAEP.
To re-encrypt all internally-encrypted data using OAEP:
Get the latest WUM updates (later than the update level released on 18/04/2018) for your WSO2 BPS 3.6.0. This will give you a new WSO2 BPS distribution with the latest updates.
Connect the WUM-updated WSO2 BPS distribution to your existing databases (which are used for registry data, and user management data):
Be sure that the
carbon.propertiesfile is included in the
<WUM_UPDATED_BPS_3.6.0_HOME>/repository/conf/directory with the following parameter:
- Start the WUM-updated BPS server. This will re-encrypt the data in the databases.
Migrating the configurations
Do not copy configuration files directly between servers. Instead, update the files manually.
To migrate all the required folders, files, libraries, etc. from WSO2 BPS 3.6.0 to WSO2 EI 6.5.0:
Copy the database connector JAR files stored in the
<BPS_HOME>/repository/components/libdirectory to the
<EI_HOME>/libdirectory of WSO2 EI 6.5.0. For example, the JAR for the Oracle database (
ojdbc7.jar) can be copied.
- Copy the keystores and truststores from the
<BPS_HOME>/repository/resources/securitydirectory to the
- If you have secondary user stores created for WSO2 BPS 3.6.0, you need to copy the 'userstore' folder in the
<BPS_HOME>/repository/deployment/server/directory to the
To migrate the configuration files from WSO2 BPS 3.6.0 to WSO2 EI 6.5.0:
- Update the configuration files with information of the migrated keystores and truststores. See Configuring Keystores in WSO2 products for more information.
- Go to the
<EI_HOME>/wso2/business-process/conf/datasourcesdirectory and update the Carbon datasource configuration in the
.xml file with the details of the Carbon database.
- Go to the
<EI_HOME>/wso2/business-process/confdirectory and update the datasource references in the
registry.xmlfiles to match the updated configurations in the
- Go to the
<EI_HOME>/wso2/business-process/conf/datasourcesdirectory and update the files relevant to your BPMN/BPEL database:
- If you are using BPMN, update the
activiti-datasources.xmlfile with the datasource connection details.
- If you are using BPEL, update the
bps-datasources.xmlfile with the datasource connection details.
- If you are using BPMN, update the
<EI_HOME>/wso2/business-process/conf/humantask.xmlfile and change
false. You can see the deployed humantask packages with the version in the console. A migration success message is printed once the migration completes successfully.
Check for any further configurations that were done for WSO2 BPS 3.6.0 based on your solution. For example, update the following configurations in WSO2 EI 6.5.0 accordingly:
Check the configurations related to external user stores, caching, mounting, transports etc.
Follow the steps given below:
- Copy the BPEL .zip packages in the
<BPS_HOME>/repository/deployment/server/bpeldirectory to the
Copy the BPMN .bar packages in the
<BPS_HOME>/repository/deployment/server/bpmndirectory to the
- Copy the humantask .zip packages in the
<BPS_HOME>/repository/deployment/server/humantasksdirectory to the
- If you have custom artifacts created in the
<BPS_HOME>/repository/deployment/server/directory of WSO2 BPS 3.6.0, copy them to the
- If you have used multitenancy, copy the tenant directory packages from
Starting the server
Once you have completed the migration, you can start the Business Process profile of WSO2 EI. For details see Running the Product.
