The successful email migration batch

With the augmenting usage of cloud computing, numerous businesses are switching to Office 365 for its communications, collaboration, and cloud-based productivity capabilities. But migratory systems can cause headaches and frustration as they move along new and old platforms.

Your employees may feel left out if they are suddenly told to change their email systems, and you need to make sure your data is secure during the relocation – data migration process. Plus, migrations can take weeks to months.

Elements to ponder when deciding to perform an Office 365 migration type

When it comes to deciding between Office 365 migration types, there are a few questions to ask yourself, such as:

  • How long do I require to migrate?
  • How big is my migration budget?
  • How much of the data do I need to migrate (relocate)?
  • Which current email system am I utilizing?
  • Which version of Exchange Online Server am I operating?

After you give an appropriate answer to these questions, you can determine the best type of migration for your organization. If your organization has multiple mailboxes and you choose to go with Cutover migration, all your users will migrate to Office or Microsoft 365 at once. 

That being said, you will need to reconfigure all of their Outlook accounts once the migration is complete, making it a poor choice if your clients need selective or seamless migration for their users. Provides no means of selectively migrating on-premises Exchange Server objects to a room.

Office 365 migration types

Staged migration

You can move all your resource mailboxes and existing users from Exchange 2003 or 2007 to Exchange Online user mailboxes with staged migration. Office 365 migration migrates everything in batches. Phase migration moves mailboxes into groups over some time. It would be best to use the directory synchronization tool, which replicates your Active Directory on-premises database accounts.

By the completion of the process, all mailboxes will be hosted in Office 365. During the migration process, Office 365 users will still be able to send and receive emails from users who have not yet proceeded with the migration process. However, the only resources that users will not be able to access are our calendars and delegates.

Cutover migration

Irregular migration is a direct transition from the Exchange 365 on-premises Exchange Admin Center. All your resources are migrated, including mailboxes, contacts, and distribution groups. With this migration, you can not select specific objects to migrate.

This Office 365 migration approach is best if you currently operate Exchange 2003 or more recent versions and have less than 2,000 mailboxes. Microsoft recommends cross-migration for companies with less than 150 users by the time it takes to migrate so many accounts.

Hybrid Migration

You are even able to pick and choose which mailboxes to store on your premises and which to migrate to Office 365. Plus, you can sync passwords and enter a single login for your team to log in to both environments quickly. If you need to employ hybrid migration, you need more than 2,000 mailboxes.

If you do not do this, you must have at least one server installed on your Exchange 2013 active users, for instance, on-premises, to enable hybrid deployment. It is also necessary to have Exchange 2010 or later.

IMAP Migration

While the other three types of Office 365 migration depend solely on on-premises Exchange organization, IMAP (Internet Protocol) migration allows you to transfer users from Gmail or any other email system that supports IMAP migration. IMAP migration draws information from your original mailboxes and passes it to Office 365.

Yet, IMAP mailboxes migration does not transfer anything other than email. Calendar items, tasks, and contacts remain in the original inbox and must be migrated manually.

Do not miscalculate the time it will take to move all of your data over

Depending on several factors, including how many users you have, how much data each mailbox has stored, bandwidth limits, and more, email migration to the cloud can take days to weeks. An unforeseen deceleration may come from Microsoft itself – a noticeable security feature of Exchange Online is that it suppresses persistent inbound links to prevent a small number of bad actors from taking over the system.


Organizations worldwide are quickly embracing Microsoft 365 because of the benefits it offers. Unfortunately, there are various management and security features that Microsoft 365 supports.

To address Microsoft 365 vulnerabilities, organizations need a third-party tool that improves security and compliance, simplifies managing Exchange Online and Azure AD, and facilitates Microsoft 365 migration.

Transition time is always challenging, which is undoubtedly true when migrating your organization to Exchange Online. You’ll make that path smoother and reach the pick more quickly by factoring in the advice and warnings regarding hosted Exchange migration to Office 365 above.
