Key Features
The calendar migration includes several important capabilities:
Delta Synchronization
Incremental updates during multiple migration passes ensure newly added appointments are captured.
Appointment Links Preserved
Organizational relationships are maintained so cancellations properly propagate to all attendees.
Resource Management
Rooms and equipment appointments are migrated with proper resource associations.
Access Control Transfer
Calendar permissions and delegation settings are preserved during migration.
Comprehensive Scope
Both primary and secondary calendars are included in the migration scope.
Email Address Conversion
The platform offers a powerful "Convert Email Addresses" setting that automatically rewrites email addresses in:
- Permissions and sharing settings
- Organizer fields
- Recipient/attendee lists
This conversion uses the migration roster as a reference table, mapping source addresses to target addresses.
Critical for Meeting Editing
Timezone Configuration
Proper timezone configuration is essential for accurate calendar migration.
Before Migration
Ensure mailbox timezones are correctly configured on the target platform before migration. Incorrect timezone settings can cause calendar entries to appear at wrong times, potentially affecting all-day events and recurring meetings.
Platform-Specific Notes
Google Workspace Migrations
- Secondary calendars transfer with their multiple owners preserved
- The system designates one owner as primary and migrates to that mailbox
- Other owners maintain access through sharing permissions
- Important: Calendar migration does not propagate changes or deletions to appointments after migration
Zimbra Migrations
Secondary calendars are excluded from Zimbra migrations. Only primary calendars are migrated.
Known Limitations
Be aware of these calendar migration limitations:
Changes and deletions made on the source after migration do not automatically sync to target appointments.
Calendar entry attachments do not transfer during migration. Users should save important attachments before migration.
