Migration Guide

Migrate from uBlock Origin

All Browsers

Planning to transition from uBlock Origin to Ghostery? This guide helps IT administrators plan and execute a smooth migration.

Manifest V3 Deadline

Chrome is phasing out Manifest V2 extensions. uBlock Origin's full version will stop working in Chrome. Plan your migration now to avoid disruption.

Why Migrate?

Manifest V3 Compatibility

Chrome's transition to Manifest V3 significantly impacts ad blockers. Ghostery is built on Manifest V3 from the ground up, ensuring:

  • Continued functionality as Chrome phases out Manifest V2
  • No disruption to your ad blocking coverage
  • Compliance with Google's extension platform requirements

Enterprise Support

  • Dedicated enterprise support team
  • Managed storage policies for centralized configuration
  • Custom builds for specific requirements
  • SLA-backed support options

Migration Checklist

Test Before Deploying

Always test Ghostery with a pilot group before organization-wide deployment. This helps identify any site compatibility issues specific to your environment.

Pre-Migration

  • Inventory current uBlock Origin deployments (browsers, platforms, policy settings)
  • Identify any custom filter lists in use
  • Document any sites currently whitelisted
  • Determine Ghostery policy requirements (lockdown level, trusted domains)
  • Test Ghostery in a pilot group

Migration

  • Deploy Ghostery using your existing management tool (same method as uBlock Origin)
  • Configure managed storage policies
  • Add trusted domains (equivalent to whitelist)
  • Remove uBlock Origin from force-install policies

Post-Migration

  • Verify Ghostery is installed on all target devices
  • Monitor helpdesk tickets for any issues
  • Update documentation and runbooks

Policy Mapping

If you used uBlock Origin with custom configurations, here's how to map common settings:

uBlock Origin Setting Ghostery Equivalent
Whitelist/Trusted sites trustedDomains policy
N/A disableUserControl - lock down user access
N/A disableOnboarding - skip setup wizard

Deployment Strategy

Option 1: Parallel Deployment

  1. Deploy Ghostery alongside uBlock Origin initially
  2. Test and validate in production
  3. Remove uBlock Origin after confirmation

Pros: Safe, allows rollback. Cons: Temporary resource overhead.

Option 2: Direct Replacement

  1. Remove uBlock Origin and deploy Ghostery in one policy update
  2. Users get Ghostery on next browser restart

Pros: Clean transition. Cons: Brief gap in coverage during transition.

Option 3: Phased Rollout

  1. Migrate pilot group first
  2. Expand to departments progressively
  3. Complete organization-wide migration

Pros: Lowest risk, allows learning. Cons: Longer timeline.
