Take Free AssessmentMigration Methods
Organizations can choose from multiple migration approaches based on their technical capabilities, timeline requirements, and specific organizational needs. Each method offers different trade-offs between automation, control, and complexity.
Method 1: Proton Easy Switch
Proton's Easy Switch tool provides the most straightforward migration path for most organizations, offering automated transfer of emails, contacts, and calendars.
Requirements
- •Paid Proton plan (Plus, Professional, or Business Suite)
- •Google account credentials with appropriate permissions
- •Stable internet connection for duration of import
Step-by-Step Process
Capabilities
- Imports all emails from Inbox, Sent, Starred, Important, and All Mail folders
- Transfers Gmail labels as Proton labels (flattens hierarchical structures)
- Migrates contacts with standard fields
- Imports calendar events with dates, times, and descriptions
- Operates server-side without consuming local bandwidth
Limitations
- Does not transfer email filters, signatures, or forwarding rules
- Flattens nested Gmail label hierarchies into single-level labels
- Cannot migrate Google Drive files (only email attachments)
- Does not preserve Gmail conversation threading exactly
- Limited to paid Proton accounts only
Handling Label Structure Changes
Gmail's hierarchical labels (Projects → Active → Client A) import as flat labels (Projects-Active-Client A). Organizations with complex label systems should plan for manual reorganization: 1) Create folder structure in Proton Mail matching desired hierarchy, 2) Move emails from imported labels into appropriate folders, 3) Apply new labels as needed for organization, 4) Budget 2-4 hours for users with extensive label systems.
Method 2: IMAP Migration Using Proton Bridge
For organizations requiring granular control or migrating selected emails rather than complete mailboxes, IMAP-based migration provides flexibility at the cost of increased complexity.
Requirements
- •Paid Proton plan with Bridge access
- •Proton Bridge application installed on Windows, macOS, or Linux
- •IMAP enabled in source Gmail account
- •Email client supporting IMAP (Thunderbird, Outlook, Apple Mail)
Step-by-Step Process
Advantages
- Selective migration of specific folders or date ranges
- Greater control over folder structure and organization
- Ability to preview and verify emails before final migration
- Works with free Proton accounts (though Bridge requires paid plan)
Limitations
- Bandwidth limited by internet connection speed (typically slower than Easy Switch)
- Google rate limits: 2,500MB daily downloads, 500MB daily uploads
- Large mailboxes may require weeks to complete
- Labels may not transfer reliably or preserve hierarchy
- Requires technical knowledge to configure properly
- Must keep computer running during entire migration process
Bandwidth Management
For large migrations, implement these strategies to avoid rate limiting: Migrate during off-peak hours (evenings, weekends), space migrations across multiple days, migrate highest-priority emails first, keep only one IMAP client connected per account.
Method 3: Third-Party Migration Tools
Professional migration platforms offer advanced features for complex migrations, particularly beneficial for large organizations or those with specific requirements.
Available Tools
Typical Features
- •Bulk migration of multiple users simultaneously
