For organizations who are switching from exchange to a cloud environment is a necessary step to enhance your business framework. A migration can be a stressful task if it is carried out in office timings which can have downtime.
Businesses who need to make sure that their employees do not suffer this downtime can get the help of an Office 365 migration tool to keep their mailbox running through the migration.
Migrate mailbox data (Exchange) to Office 365
One of the most visible aspects of an Office 365 implementation is the migration of e-mail data into the Exchange Online system. To begin a migration, you use the E-Mail Migration page. You can access this page by clicking the Manage link under the Exchange Online section on the main Office 365 management page and then clicking the E-Mail Migration button.
To begin a new migration, click the New tab to begin walking through the Migration wizard. The Migration wizard will let you migrate your Exchange settings. If you are migrating from Exchange 2007 or later, the wizard will use Autodiscover to autodetect settings. If you are migrating from Exchange 2003 or IMAP, then you need to enter the settings manually.
After completion of a migration, user e-mail will be available in the Office 365 system.
Estimated migration times
When you’re doing a Microsoft Office 365 migration, all mailboxes are migrated within Microsoft 365 data centers, every mailbox move or bulk-mailbox move requires time for the operation to complete. There are a number of factors, such as Microsoft 365 service activity, that can affect exactly how much time. The service is designed to throttle discretionary workloads like mailbox moves, to ensure that the service runs optimally for all users. You can still expect mailbox moves to be processed, however, depending on the service’s discretionary resource availability.
Migrations for less than 500 users
In an Office 365 tenant to tenant migration there can be a cut-off date that can help limit the volume of data migrated. One can fix up a specific period, say six months for migrating mail, calendar data, and contact information.
Migration for more than 500 users
The IT admin team can adopt a multi-pass approach in this case. As the migration process can take time, one can migrate calendar, email, and contact information for one week. The users can start functioning on the new target domain while the balance data migration takes place in the background.
