Version: ShareGate Migrate 24.10.0
Release Date: 2 October 2024
What's fixed
We resolved an issue in which migrating many messages with Copy mailboxes could randomly fail due to an irresolvable conflict error.
We fixed an issue where starting Copy mailboxes with a large number of mailboxes (i.e., more than 250,000) would cause the migration process to freeze or take an excessively long time.
We fixed a Copy mailboxes issue where clicking the Clear all button on the source mailboxes screen caused the application to freeze for minutes in environments with many mailboxes.
To improve the performance of Copy mailboxes, ShareGate Migrate only copies special occurrences of recurring events (cancelled or exception) starting today or in the future.
This change also solved an issue where invitees would incorrectly receive email notifications for modified past occurrences of recurring meetings during calendar migrations.
The Copy mailboxes mapping screen now loads previously defined mappings, including internal recipients, during subsequent Copy mailboxes operations between the same source and destination tenants.
