1. Planning and Preparation
a. Define Objectives

  • Identify the goals of migration (e.g., enhanced functionality, better user experience).
  • Document the scope, including which modules and data will be migrated (e.g., Incident, Change, Problem, Knowledge).

b. Form a Migration Team

  • Assemble a team of subject matter experts, developers, and administrators for both BMC Remedy and ServiceNow.

c. Assess Existing BMC Remedy Environment

  • Review current workflows, business rules, customizations, and data architecture in BMC Remedy.
  • Identify obsolete or redundant processes and data to exclude from migration.

d. Define Target Architecture in ServiceNow

  • Determine the ServiceNow modules to use.
  • Design workflows and data models that align with ServiceNow's best practices.

e. Develop a Migration Plan

  • Establish a detailed project timeline.
  • Decide on the migration approach (Big Bang or Phased).
  • Identify potential risks and mitigation strategies.

2. Prepare ServiceNow Instance
a. Activate Required Modules

  • Enable the necessary ServiceNow plugins/modules (e.g., ITSM, CMDB).

b. Configure Roles and Permissions

  • Set up user roles and permissions to match the business requirements.

c. Customize ServiceNow Workflows

  • Configure workflows, forms, and business rules in ServiceNow to mirror or improve upon the existing processes in BMC Remedy.

d. Develop Integrations

  • Establish integrations with external systems (if any), such as email, Active Directory, or monitoring tools.

3. Data Migration
a. Analyze Data in BMC Remedy

  • Map BMC Remedy fields to corresponding ServiceNow fields.
  • Document data transformations needed (e.g., field type conversions).

b. Extract Data

  • Use BMC Remedy APIs, database queries, or export tools to extract data.
  • Export data incrementally to avoid performance issues.

c. Clean and Transform Data

  • Remove obsolete, redundant, or invalid data.
  • Transform data into a format compatible with ServiceNow's data model.

d. Import Data into ServiceNow

  • Use ServiceNow's Import Sets and Transform Maps for data migration.
  • Test with small data sets before importing the full dataset.

e. Validate Data

  • Cross-check the migrated data in ServiceNow against the source in BMC Remedy.
  • Resolve discrepancies or errors.

4. Process Reengineering
a. Review Existing Processes

  • Compare BMC Remedy workflows with ServiceNow's capabilities.
  • Identify opportunities for optimization.

b. Align Processes with ITIL Best Practices

  • Use ServiceNow's ITIL-aligned modules to standardize processes.
  • Reconfigure workflows for improved efficiency.

5. Testing
a. Unit Testing

  • Validate individual data imports, workflows, and integrations.

b. System Testing

  • Test the end-to-end functionality of all modules and integrations.

c. User Acceptance Testing (UAT)

  • Engage end-users to verify that the migrated system meets business requirements.
  • Gather feedback and make necessary adjustments.

6. Training and Documentation
a. Train Users

  • Provide training for end-users on ServiceNow functionality.
  • Offer role-specific training for administrators and developers.

b. Update Documentation

  • Create detailed documentation for processes, workflows, and configurations in ServiceNow.

7. Go-Live
a. Schedule Migration

  • Plan the go-live during a low-activity period to minimize disruption.
  • Notify stakeholders of the migration timeline.

b. Perform Final Migration

  • Execute the final data migration, including any delta changes since the initial migration.
  • Validate the migrated data once again.

c. Switch to ServiceNow

  • Redirect users to ServiceNow and disable BMC Remedy access.

8. Post-Migration Activities
a. Monitor Performance

  • Continuously monitor system performance and resolve any issues.

b. Gather Feedback

  • Collect feedback from users to identify areas for improvement.

c. Optimize Workflows

  • Refine workflows and configurations based on real-world usage.

d. Decommission BMC Remedy

  • Archive historical data from BMC Remedy if necessary.
  • Decommission BMC Remedy once all critical operations are confirmed to be functional in ServiceNow.

Tools and Techniques

  • ETL Tools: Tools like Boomi, MuleSoft, or custom scripts for data extraction and loading.
  • ServiceNow Import Sets: For importing and transforming data.
  • API Integrations: For real-time or incremental data migration.
  • Testing Tools: Use tools like Selenium or ServiceNow ATF (Automated Test Framework) for testing.
