For many businesses, Exchange 2010 has been a reliable Mail Server, which hosted and looked after the millions of emails that are sent around the world. However, like many products, they all have a support lifecycle which comes to an end and they need to be replaced. Originally announced for 14th January 2020, Microsoft changed the Exchange 2010 End of Life date to 13th October 2020. 

Whether you used it as on-premise server or as a SaaS package, the time is now to start thinking about your future mail server, whether that’s Office 365 or Exchange 2016. This blog will give you all the end of support advice you need ahead of your email migration.

What does End of Support mean?

Every Microsoft product has a life cycle where the company provides new features, updates, bug fixes and security fixes to keep them running. This extended support lifecycle typically lasts for 10 years from the day the product is launched. On 13th October 2020, Microsoft will no longer provide:

  • Technical support on Exchange 2010
  • Bug fixes for stability and usability issues that may occur while using Exchange 2010
  • Security updates that make the mail server vulnerable to security breaches
  • Time zone updates

If you have an installation of Exchange 2010, it will continue to be usable after 13th October, however, it is strongly recommended that you migrate to a new mail server before the end of life date. Failure to do so will leave you and your email data vulnerable to a cyber attack. In this instance, your business would fail industry regulations.

Migration Options

With Exchange 2010 now reaching the end of its lifecycle, it’s vital to explore what options are available to you regarding migration. If you plan to stay with Microsoft’s mail servers, you can:

  • Migrate to Office 365 
  • Migrate Exchange 2010 on-premises servers to Exchange 2016

Office 365 Migration

The easiest way for any business to retire their Exchange 2010 deployment and move to a new system is with Office 365. Doing so will support digital transformation by moving your business from older technology to a modern cloud-based mail system. Office 365 has all the latest features and experiences which users can benefit from straight away. It also means you’re always on the latest version of Exchange in Office 365.

There are three types of Office 365 migration – Cutover, Express or Full Hybrid.

Cutover Migration – 150 seats or less

A cutover migration is the process of migrating all mailboxes, distribution groups, contacts and more to Office 365 on a pre-selected date and time. Once completed, your Exchange servers are shut down and Office 365 becomes your exclusive mail server. This process is recommended for small businesses that have 150 user mailboxes or less because the process is quite simple compared to the other two methods. Users will need to recreate their Outlook profiles on the new system.

Express Migration – 150 seats or less

An express migration is perfect for those smaller businesses that need to take time on their migration. Express migration offers some benefits of the hybrid migration, but without its complexities. This gives you full control over the mailboxes that are migrated at any given time. The express process also carries over the usernames and passwords of users from the on-premises accounts, meaning users get a seamless transition.

Full Hybrid – 150 seats or more

A full hybrid migration is needed for organisations with hundreds and even thousands of mailboxes to move. Deploying a hybrid solution means that you can move a number of mailboxes at a time while retaining some on the current server. This is vital for a large organisation because of the amount of time needed to move that many mailboxes over.

Exchange 2010 to 2016 Migration

Some organisations must keep emails on-premises for regulatory purposes, which is why they need to migrate Exchange 2010 to 2016. Because Office 365 stores information on a data centre, not every business can do that or don’t feel comfortable doing so. 

You can migrate your current Exchange 2010 environment to Exchange environment over to Exchange 2016 and benefit from the features and enhancements that match the experience found in Office 365.

The process is usually as follows:

  • Install Exchange 2016 into the existing Exchange 2010 organisation
  • Move your services and other infrastructure to Exchange 2016
  • Move all mailboxes and public folders to Exchange 2016
  • Decommission your Exchange 2010 servers

Email Archiving and Migration

Email archiving can support businesses who need to migrate to a new system. By uploading your mailboxes into an archive, you can use the sophisticated search options to find the information and mail you need to carry over. By cutting the amount of unnecessary data you carry over, it will ensure a faster and more efficient migration. With the support of Cryoserver and the CryoCloud, we’ll also help identify the best type of migration for your business.
