Transcript

Determining an email migration path to Office 365 can be tricky. In this lesson, we'll cover some different migration planning options that are based on the source email system, as well as some other factors. 

Before beginning an email migration, it's important that you first review the limits and Office 365 performance and best practices guide for Exchange Online. Then you can be sure that you get the performance and behavior that you're expecting after an email migration. 

Since you can migrate mailboxes from Exchange as well as other email systems, we'll break things down by email system. 

Migrating from an existing on-prem Exchange Server environment allows you to migrate all mail, calendar items, tasks, and contacts to Office 365. 

There are three key types of migration methods available. They include the cut over migration, the staged migration, and Exchange Hybrid migrations. You can also use IMAP migrations as well. 

The Exchange Hybrid option can be further broken down into two sub types. Minimal Hybrid, which is also known as express, and Full Hybrid. 

The cut over, staged, and Hybrid options will copy over all mail, all contacts, calendar items, and tasks. 

However, the fourth option IMAP, will only copy over mail data. It's also important to note, that if you're on-prem Exchange organization is older then Exchange 2003, your only migration option is going to be IMAP. The staged and Exchange Full Hybrid migration options, require directory sync to be set up, which does make them a little more complex to plan and implement. 

The Minimal Hybrid, or express migration, can only be used if there will be no ongoing directory synchronization necessary. Essentially what this means is, if you plan to use directory sync one time to get your users staged into Office 365, and then subsequently turn it off, that's the only case where you could use a Minimal Hybrid. 

So, essentially, if you plan on continuing to manage your users on-prem through an on-prem Active Directory, for example, a Minimal Hybrid or express would not be a good option.
