When a business is accessing email and data from an on-premise server, the users can only access it when on the same network as the server, which means that they have to be in office to gain access to email and data, or implement and maintain a VPN. This is not working for most businesses anymore and why they are coming to us to get them off of a server and into the cloud.

Migrations from a server into the cloud are among some of the most involved and there are multiple ways to get it done. Keep reading to learn more about the process and the advantages/disadvantages of both.

Migrate - The staged migrations can begin to Migrate Email from Hosted Exchange to Office 365 and mailboxes are converted to Exchange Online mailboxes.
Migration complete - All mailboxes have been converted to Exchange online and mailflow is directed to O365/hybrid. Exchange on-prem can be decommissioned if desired.
Here are the pros and cons of this type of on-prem migration into the cloud:


Less end user impact
Migration can take place at the customers pace
Migration can be done in groups instead of all at once

Next, let's take a look at a full O365 Migration. This type of migration takes the on-prem server completely out of the end result. Here is the process:

Set up O365 tenant and sync accounts - AD Connect is used to sync accounts over from Active Directory. 
Obtain server administrator credentials - We need this, and other necessary server data, to access the data on the server to migrate.

Set up the migration batch to Office 365

Complete data migration - Customer confirms that all data looks good and the mail cutover is performed. Any connected mail applications and devices will need to have new profiles set up that connect to Office 365 mailboxes.
Here are the pros and cons of this type of on-prem migration into the cloud:


Generally a faster migration
No need for deploying hybrid
Negates hybrid maintenance and trouble shooting of any issues that arise
