Move email platforms without losing a single message.
Email platform migrations carry real risk of data loss and service disruption. IP Four manages the entire process from assessment to cutover, preserving every email and keeping your team productive throughout.
Migration and backup built for zero data loss.
From zero-downtime migration to point-in-time recovery, every capability is designed to protect your email data through platform changes and unexpected incidents.
Zero-Downtime Mailbox Migration
Mailbox migrations executed with no interruption to email service. Cutover windows planned for minimum business impact. Users continue sending and receiving throughout the migration process.
Archive History Preservation
Full email history migrated alongside live mailboxes. Archive metadata, folder structures, and timestamps preserved exactly. No loss of historical email during platform transitions.
Cross-Platform Migration
Migrations from on-premise Exchange, Google Workspace, Lotus Notes, and other platforms to Microsoft 365 or hosted Exchange. All source platforms supported with full data fidelity.
Automated Mailbox Backup
Daily automated backup of all mailboxes including sent items, calendar, contacts, and tasks. Backups stored in UK data centres separate from your primary email platform.
Point-in-Time Recovery
Restore individual emails, folders, or entire mailboxes to any point in time within the backup retention period. Recovery available within minutes for individual items, hours for full mailboxes.
Leaver and Joiner Mailbox Management
Leaver mailboxes archived and retained for the required period before deletion. Joiner mailboxes provisioned with access to relevant historical email. Handover processes managed automatically.
From migration assessment to protected mailboxes.
Migration Assessment
Source platform, mailbox count, archive size, and migration complexity assessed. Risks identified and mitigation planned. Migration timeline and cutover window agreed with your team.
Pre-Migration Preparation
Source and destination platforms prepared. Test migration of sample mailboxes validates data fidelity. Rollback procedures documented. User communication plan agreed.
Phased Migration Execution
Mailboxes migrated in batches to manage risk. Archive history migrated in parallel with live mailboxes. Progress reported daily. Issues resolved before proceeding to next batch.
Cutover and Validation
Final cutover executed during agreed window. DNS and mail routing updated. All users validated on new platform. Rollback available for 48 hours post-cutover.
Backup Configuration
Automated backup configured for all migrated mailboxes. First backup completed and verified. Recovery testing performed on sample mailboxes. Backup monitoring alerts configured.
Ongoing Backup Management
Daily backup monitoring with alerts for any failures. Monthly backup health reports. Annual recovery testing. UK-based support for recovery requests within agreed SLAs.
How we have helped UK businesses migrate safely.
On-Premise Exchange to Microsoft 365
A Manchester professional services firm needed to migrate 120 mailboxes from on-premise Exchange 2013 to Microsoft 365 without losing 8 years of email history or disrupting their busy client-facing team.
All 120 mailboxes migrated with full 8-year history preserved. Zero emails lost. Cutover completed over a weekend with no Monday morning issues. Microsoft 365 backup configured on day one.
Google Workspace to Microsoft 365 Migration
A Birmingham technology company acquired a Leeds firm running Google Workspace. They needed to consolidate onto Microsoft 365 while preserving all historical email from both organisations.
Both organisations migrated to unified Microsoft 365 tenant. All historical email preserved with original timestamps. Users operational on new platform within 3 weeks of project start.
Ransomware Recovery via Backup
A Leeds accountancy firm suffered a ransomware attack that encrypted their Microsoft 365 mailboxes. Microsoft native backup was insufficient to recover emails deleted by the attacker.
All mailboxes restored from independent backup to the point immediately before the attack. Zero email data lost. Recovery completed within 4 hours of the incident being reported.
