Key Migration Steps
1. Preliminary Inventory and Audit
Before any migration, we conduct a complete inventory:
- Number of mailboxes and size of each
- Existing aliases and redirections
- Shared calendars and contacts
- Filter rules and signatures
- Connected devices (PC, Mac, smartphones)
Key Point
The preliminary audit helps anticipate difficulties and define a realistic schedule. This is a step we perform free of charge.
2. Preparing Infomaniak Accounts
Once the audit is complete, we create the target environment:
- Setting up the Infomaniak Mail Service
- Configuring mailboxes with the same addresses
- Setting up aliases and redirections
- Configuring appropriate quotas
Mail Service from €1.50/month
Infomaniak Mail hosting offers professional mailboxes with anti-spam, antivirus, and a modern webmail interface.
3. Data Migration
This is the main technical step. We use professional tools that allow us to:
- Transfer all emails with their folder structure intact
- Preserve metadata: dates, flags, read/unread status
- Migrate in the background while you continue using your old email
4. Calendar and Contact Synchronization
Calendars and contacts are often trickier to migrate than emails. We use CalDAV and CardDAV protocols to ensure a complete migration:
| Item | Source (Microsoft 365) | Destination (Infomaniak) |
|---|---|---|
| Main calendar | Exchange Online | CalDAV |
| Shared calendars | Exchange permissions | CalDAV sharing |
| Contacts | Exchange address book | CardDAV |
| Shared contacts | Shared mailbox | Shared address book |
5. DNS Switch and Go-Live
On D-day, we update the DNS records (MX) to redirect the email flow to Infomaniak. This operation is planned to minimize impact:
- Usually performed in the evening or on weekends
- DNS propagation monitored in real time
- Temporary dual reception to avoid losing anything
User Workstation Configuration
Migration doesn\'t stop at the server. Each user\'s software and devices also need reconfiguring:
Outlook (Windows/Mac)
We set up a new IMAP/SMTP profile with Infomaniak settings. The old Exchange profile is temporarily kept for reference.
Apple Mail (Mac/iPhone/iPad)
Configuration is simpler thanks to automatic detection. We simply add the mail account with CalDAV/CardDAV sync.
Android Smartphones
Configuration via the Gmail app or a dedicated mail app. Contacts and calendars are synced through CalDAV/CardDAV accounts.
How Long Does a Migration Take?
Duration depends mainly on data volume and number of users:
Estimated Timeframes
- 1-5 mailboxes: 1-2 business days
- 5-20 mailboxes: 2-5 business days
- 20+ mailboxes: 1-2 weeks
Pitfalls to Avoid
Common Mistake
Switching DNS too early, before data migration is complete.
Our Approach
We wait until 100% of the data is synchronized before switching the DNS.
Common Mistake
Forgetting to migrate Outlook filter rules and signatures.
Our Approach
We document all existing rules and recreate them on the Infomaniak side or in the mail client.
Conclusion
Migrating to Infomaniak is an excellent decision for businesses concerned about data protection and environmental impact. With rigorous preparation and professional support, the transition goes smoothly.
