Upgrading on-premises Exchange 2003: it’s harder than you think

 

You probably know that Microsoft is ending extended support for Exchange 2003 on April 8th.

Are you considering upgrading your on-premise Exchange 2003 server to Exchange 2010 or Exchange 2013?

It’s certainly an option. But before you begin, you should know that you’re in for much more work than you may realize.

Upgrading Exchange 2003 involves more than just Exchange

An on-premises upgrade of Exchange 2003 is not a simple matter of just upgrading licenses and installing servers.

That’s because Microsoft Exchange 2010 and 2013 have fundamental differences from 2003. And these differences will require you to upgrade the surrounding network as well as Exchange itself. You’ll need to invest time, effort and money in:

  • Network topology upgrades
  • Network and datacenter security investments
  • Uptime planning and failover systems design
  • Equipment upgrades (server, data storage, etc.)
  • New software and support licenses
  • Increased management costs of a more complex technology environment

What’s more, if you’re adding or upgrading any additional collaboration services (such as Lync or SharePoint), you’ll need to make even more investments. And integrating further email services—such as email archiving and disaster recovery—will also increase the overall investment and amplify the ongoing management burden.

(Here’s a roadmap on TechNet that should help you appreciate the breadth of the complexity.)

So what are your options?
