Recently Microsoft Exchange 2013 end of life declared, which means that Microsoft will no longer provide technical support, security updates, and bug fixes, to Exchange 2013 users.  This can leave organizations using Exchange 2013 at a higher risk for security vulnerabilities and performance issues.

End-of-life support is a natural part of its lifecycle, and it is important for organizations to plan for this event to ensure a smooth transition to a more preferred platform. There can be 2 routes that a user can take in this situation. One of them is to move their data to a newer version of the Exchange Server or they could migrate their mailbox from On-Premise to Office 365 Platform i.e. Office 365.

The problem with moving to another version of Exchange like Exchange Server 2019 is that eventually, it will also reach its end-of-life support in the near future. This means that you have to perform the migration process again for the same. Hence moving your data to the Exchange online is more beneficial in the long run. 

Why is it Necessary to Migrate to Office 365 After Exchange 2013 End of Life Date Announced?

One of the biggest advantages of moving your data to Office 365 comes from the fact that it is a cloud platform. This ensures that this service would be supported for a long time and would not be discontinued after a few years like Exchange Server.

It is also important from a security point of view. If you run the Exchange server after its end of life then you might be vulnerable to different types of cyberattacks. Since all the maintenance and other factors are taken care of by Microsoft itself, they promise an uptime of 99.9% for all Office 365 services. This enables you to access your data anywhere in the world without downtime. 

Office 365 is also easily scalable if compared to an Exchange Server. This is because you can simply go up or down to an Office 365 plan depending on your needs and easily get the storage and other resources you need. But whereas on an Exchange Server, you will have to get the required hardware and the software and configure it yourself.

What Should be the Next Moves After the Announcement of  Microsoft Exchange 2013  End of Life Support?

In order to tackle this situation, users of Exchange 2013 should migrate their data to Office 365. There are few manual and automated ways available for this transition. Let’s discuss them step by step. 

Cutover Migration 

This method can be used to transfer your entire environment together to Office 365. The only drawback with this method is that the maximum number of mailboxes you can migrate at once is 2000. This method can be used with Exchange versions 2003 and higher. Even though the official maximum supported number of mailboxes it can migrate is 2000 it is recommended not to migrate more than 150 users at a time since it increases the chances of failure a lot. 

IMAP Migration 

If you are in a need where you only want to migrate your email data to Office 365 then you can use this method. But you can only migrate 5,00,000 items using this method. These items have to be less than 35MB in size. Before the migration, the IT admin also needs to make a CSV file that has the list of the users you want to migrate.
