The migration from Exchange 2010 to Office 365 is on everyone's lips. Office 365 is a cloud-based software as a service that has numerous user-centric features and services. It has much more to offer you. Unfortunately, Exchange Server users have limited manual method to migrate Exchange 2010 to Office 365.

Exchange 2010 to Office 365 migration cutover migration:
If you have less than 200 mailboxes on your Exchange Server, the cutover migration process is the perfect solution for Exchange 2010 to Office 365 migration. This can be done using the setup wizard or via EAC (Exchange Admin Center). The setup wizard only allows users to move 150 mailboxes. You can also move 2000 or more mailboxes using Exchange Admin Center.
Learn more about the cutover method:
First, you need to open the Exchange Deployment Assistant website. It covers all Exchange 2010 to Office 365 migration scenarios. Use cloud-only option for better response.
Now it should be checked whether the server infrastructure of Exchange 2007 supports MS Outlook Anywhere and the automatic detection. Use the guide to then authenticate the Exchange Server 2007 setup. After verifying the setup, use Microsoft Remote Connectivity Analyzer and verify Outlook Anywhere. Also, the user needs to be sure that you have assigned the migration permissions for a correct account to the mailboxes to be moved.

- Click Outlook Anywhere (RPC over HTTP) test. Click Next to continue.
- Enter the required information.
- Then check using automatic detection to detect server settings.
- Now enter the verification code.
- Click Run Test.
Configuration of cutover migration process:
- First, sign in to Office 365Admin-Center.
- OpenExchange Admin Center
- Click the Migrate button.
- Then click the Plus (+) button and select the Migrate to Exchange Online option.
- Now select cutover migration and click Next.
- Enter the local account details and continue.
RPC proxy server setting is automatically selected along with Next Exchange Server. Then click Next.
- Rename the new migration batch. Click next.
A whole new oneExchange Server-MigrationBatch file will be created and you will see the status of syncing the provided information from the old file. You can review the migration details by clicking View Details under Mailbox Status.
Completion of the migration process
After migrating from Exchange 2010 to Office 365, the synchronization status changes from Syncing to Synced. You will also receive a confirmation report in the mail.
As a hybrid approach, it serves as both a migration and implementation strategy in its own right. The staged migration of Exchange 2003 and 2007 can be modernized with this new approach. It is possible to use both Exchange 2010 and Office 365 Hybrid in the same environment. If you have a lot of data to migrate Exchange 2010 to Office 365 and the process will take a long time, this option is ideal. The only native way to migrate 2000+ mailboxes is with a hybrid approach. When it comes to moving more than 150 mailboxes, hybrid is the best option.
Depending on the needs of each user, some organizations use hybrid deployment as the last tier rather than an intermediate step. In these cases, users are distributed across on-premises and online environments.
A Hybrid Configuration Wizard is used to set up the Hybrid Environment (HCW). Learn how to use the HCW and troubleshoot hybrid deployment deployments by reading thisArticle.
Exchange 2010 to Office 365 migration through PST files
The final native migration is performed by using the Office 365 PST import service. The basic concept is to export Exchange 2010 mailboxes to PST files and then import them to an Office 365 organization. This method requires some manual work on the part of the administrator. This involves virtually building an Office 365 setup from scratch.
Exporting all mailboxes to PST is a task that is best accomplished using PowerShell and the New-MailboxExportRequest cmdlet. The PST files must be shared or stored on a file server. You then need to upload them to the Azure location and create a CSV mapping file from that location. The PST import service imports PST files to the appropriate user mailboxes using the mapping file.
Microsoft also offers the option to ship physical drives to them, which means that PST files are copied to physical storage devices and sent to Microsoft. This service is charged at $2 per gigabyte of data.
The disadvantages of manual migration processes
Each of the above native approaches has some drawbacks due to which users always worry about their data during migration from native Exchange to Office 365.
Cutover Migration Limitations
A cutover migration is an all-or-nothing solution and, as mentioned above, is only recommended for up to 150 mailboxes and if you have a team of techies, otherwise a single misstep could result in your data being lost or to be damaged.
Limitations of Hybrid Migration
Transitioning to hybrid migration is a time-consuming and slow process. Just like the cutover method, you also need geeks on your team to complete this task with minimal data loss.
Limitations of migration through PST export
Ah, you think migrating Exchange 2010 to Office 365 with PST will be an easy process or quick, so let me make it clear that if you have multiple mailboxes, you don't even think about it. I don't know where to start, but this method is not convenient, not even hasty. Just like you need to migrate Exchange to PST first and use PowerShell for that in multiple steps, which is also a walk-in eggshell in itself. I only recommend this method if you only have a small amount of email to migrate and you don't mind rebuilding your Exchange 2010 environment in Office 365 from scratch.
General limitations of native utilities
Limitations don't end here as there are few limitations common to all native options such as:
- Many steps of the migration require the use of PowerShell. While it's really beneficial to know how to use this powerful scripting language, you need to have a certain level of skill. During this difficult process, spontaneous learning can be uncomfortable for you and harmful for the (server) environment.
- If the Exchange 2010 to Office 365 migration process gets interrupted, you need to restart it from the beginning.
- It is a very complex process and there is no 100% guarantee of success.
- You may have lost some files while exchanging them between servers.
- Upgrade your servers to the latest version for the best migration experience. It is recommended to upgrade to Exchange 2010 SP3. Therefore, if you have not upgraded your machines, you should schedule some maintenance work.
- Downtime is inevitable, especially when migrating public files. You need to plan carefully, especially when the resources on your servers are used continuously.
- No filtering is available. Both cutover and hybrid migration enable filtering of Office 365 items that are transferred.
