Does QMM 8.8 support using multiple agents when migrating from Exchange to Office 365?
QMM version 8.8 does not support multiple MAEO agents for Exchange to Office 365 migrations.
When migrating from Exchange to the Office 365, the migration of mailboxes is managed by a PowerShell "pull" command from the CAS servers in the cloud. The QMM MAEO agent initiates the process and monitors progress, but does not control the batch. Microsoft controls how much, and how fast, mail items are migrated to the cloud from the source Exchang org, and current architecture allows for only one migration batch to be running per target Office 365 Exchange org.
To improve performance, contact Microsoft Office 365 support to request Office 365 throttling limits to be increased. Increasing the batch size and number of concurrent mailboxes may also help. For more information on batch size, review Solution 86973.
QMM version 9.0 and later will no longer use the native MSFT tools for Office 365 migrations, but will employ agents which "push" the data. This architecture will support multiple agents and improve Exchange to Office 365 performance.
