1 About the WebLogic Migration (OWM) Tool

The OCI WebLogic Migration (OWM) Tool enables lift-and-shift migration of single or multi-node WebLogic domains from on-premises environments to Oracle Cloud Infrastructure (OCI), optionally fronted by a load balancer.

Use this tool if you need to migrate an existing WebLogic domain to OCI and want help with:
  • Discovering the current WebLogic domain configuration.
  • Discovering infrastructure referenced by the domain, including machines, clusters, managed servers, applications, and resources.
  • Discovering JDBC datasources and generating OCI Resource Manager inputs.
  • Building an OCI Resource Manager stack bundle.
  • Archiving WebLogic, Java, domain, and custom directory assets. Optionally uploading generated artifacts to OCI Object Storage.

Key features of the tool:

  • The tool inspects the existing WebLogic Domain to discover domain configuration, managed servers, clusters, applications, and resources.
  • Based on this discovery, it generates a tailored Resource Manager stack that leverages OCI Resource Manager to securely provision and configure:
    • OCI Networking resources (VCN, subnets, gateways, route tables, and security lists)
    • Compute Instances to host the discovered WebLogic domain
    • Optional load balancers for distributing traffic across WebLogic managed servers
  • The tool updates JDBC datasource configuration files in the domain so that WebLogic servers in OCI can connect to target databases.
After a successful run, the tool can generate:
  • A WebLogic discovery JSON file, such as `out/Discovered_<timestamp>.json`.
  • An infrastructure discovery JSON file, such as `out/infra_output_<timestamp>.json`.
  • Datasource-related Terraform and schema files under `oci/generated/`.
  • An OCI Resource Manager stack ZIP under `oci/stack/`, such as `owm_rm_<timestamp>.zip`.
  • Migration archives under `out/`. - Run status and output metadata in `logs/migration_data.json`.
  • Optional OCI Object Storage uploads and a Pre-Authenticated Request (PAR) URL for the generated stack ZIP.

Important:

Important: This tool does not migrate on-premises databases to OCI. Database migration must be completed separately, and the resulting OCI database connection details must be supplied during the migration or Resource Manager workflow.
