Introduction to Migrating IDM Data with “migration.json”
In the fast-paced digital environment, regularly updating your Identity Management (IDM) system is essential to maintain security, efficiency, and connectivity. Carefully planning the migration of IDM data is crucial to ensure a smooth transition. This blog post will guide you through using the “migration.json” approach to migrate important data entities like “links,” “relationships,” and “managed objects”, among others, when upgrading to ForgeRock IDM 7.5. Additionally, this post provides a sample migration.json configuration for those whose IDM is authenticating via ForgeRock AM using a bearer token approach. This example will help ensure that your migration process is tailored to accommodate specific authentication protocols, further smoothing the transition.
Key Steps in Enabling “migration.json” for IDM Data Migration
Obtain the Sample Migration File
ForgeRock IDM provides a sample migration.json located under samples/example-configurations/conf/migration.json. This file serves as a template that can be adapted to meet your specific migration needs. Using this template ensures that you start with a solid foundation that includes standard configurations.
Prepare the Migration File
Once you have the sample file, the next step is to copy the migration.json from the sample directory into your conf/ directory in the new IDM 7.5 installation. This positions the file in its necessary location, making it ready for further modifications and activation. Based on how your IDM is configured—for example, using bearer tokens for authentication or basic authentication—you will need to configure and enable specific properties in the migration.json to match these requirements. Here is a sample configuration using the “bearer” token approach:
{
"enabled" : false,
"connection" : {
"instanceUrl" : "https://idm.dev.com/openidm/",
"authType" : "bearer",
"clientId" : "migration-service",
"clientSecret" : "your-secret-goes-here",
"scope": [ "openid", "fr:idm:*" ],
"hostnameVerifier" : "ALLOW_ALL",
"tokenEndpoint" : "https://am.dev.com/auth/oauth2/access_token"
},
"mappings" : [
{
"source" : "repo/link"
},
{
"source" : "repo/relationships"
},
{
"source" : "repo/internal/role"
},
{
"source" : "repo/internal/user"
},
{
"source" : "repo/internal/usermeta"
},
{
"source" : "repo/managed/role"
},
{
"source" : "repo/managed/user"
},
{
"source" : "repo/managed/assignment"
},
{
"source" : "scheduler/job"
}
]
}When configuring your migration service to use bearer tokens for authentication, it’s crucial to ensure that the client has the necessary permissions. Specifically, your client must have access to the scope "fr:idm:*". Without this access, you may encounter issues during the migration call, as the client might not have sufficient permissions to perform all required actions. Make sure to verify and adjust your client’s scope settings accordingly to facilitate a smooth migration process.
Configure Mappings According to Your Use Case
When setting up your migration, it’s important to customize the migration.json mappings to fit your specific requirements. The default configuration includes mappings for various IDM components such as:
{"source" : "repo/link"}{"source" : "repo/relationships"}{"source" : "repo/internal/role"}{"source" : "repo/internal/user"}{"source" : "repo/internal/usermeta"}{"source" : "repo/managed/role"}{"source" : "repo/managed/user"}{"source" : "repo/managed/assignment"}{"source" : "scheduler/job"}
Depending on your environment, some of these components might not need to be migrated. Customize the mappings to include only those elements that are relevant to your migration to ensure efficiency and accuracy.
Enable the Service
To activate the migration service, modify the migration.json file by setting "enabled": true. This crucial step turns on the migration capabilities within IDM, enabling the service to manage and execute the data transfer process.
Secure Sensitive Data
The migration process entails the transfer of sensitive information, including passwords. To ensure that this data is accurately managed and migrated, it is crucial to transfer the truststore and keystore files from your old system to the new one before starting the migration. This essential step helps preserve the integrity and accessibility of encrypted data, enabling the new IDM installation to seamlessly decrypt and access previously encrypted information.
Reconciliation Optimization
If you’re dealing with a larger dataset to be migrated, optimizing your migration.json file becomes essential to handle the volume effectively and ensure a smooth transition. The data migration process involves not only transferring data but also ensuring that the data remains consistent and accurate across different system versions. Similar to how you would approach a typical data reconciliation, applying reconciliation optimizations to your migration.json is crucial.
Running the Data Migration
To ensure a smooth data migration to your new IDM installation, start by pausing any scheduled jobs on the source deployment to prevent new data transactions during the migration. Make sure that your configuration files, specifically conf/migration.json. Additionally, transfer all relevant configuration files from your old deployment to ensure consistency.
If your system utilizes workflows, manually export the workflow database tables, typically prefixed with ACT_, from the old deployment and import them into the new system before its first launch. This step is crucial for maintaining the workflow functionalities in the new environment.
Once everything is set up, initiate the migration by accessing the new IDM installation’s migration endpoint. You can do this by sending a POST request via tools like curl, which triggers the migration of all legacy objects. For example, you might use a command like:
curl --header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://dev.idm.com:8080/openidm/migration?_action=migrate&mapping=repoManagedUser_repoManagedUser"
OR
curl --header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://dev.idm.com:8080/openidm/migration?_action=migrate"This command starts the migration process according to your specified settings. During and after the migration, monitor the process through the migration endpoint to check the status and review the final outcomes. This helps confirm that all data, including object IDs, has been correctly transferred and that the system functions as expected in its new environment. The duration of the migration will vary depending on the amount of data being transferred, but careful planning and monitoring can help minimize disruptions.
curl --header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://dev.idm.com:8080/openidm/migration?_action=status"This status action provides real-time updates on the migration, helping you monitor progress and address any issues promptly.
