The following are the steps that I went through to upgrade the Release Candidate Version of Exchange 2010 to RTM edition of Exchange 2010.

I got my copy from TechNet and the same is available under MSDN as well.

There is also a 120 day evaluation copy available here in couple of different formats:-

  1. Virtual Experience that gives you an chance to try Exchange 2010 and OCS 2007 R2
  2. Free 120 Day Software Trial
  3. Pre-configured VHD
  4. Exchange Online

Steps involved:-

  1. Backup your server. I use Shadow Protect to backup the VM’s but also equally recommended is DPM 2007 or if you can get your hands on 2010. You can read on Shadow Protect from here
  2. Get to your Exchange 2010 RTM Setup folder and double click on setup.exe 1
  3. Choose your language pack

  4. Click on Install Microsoft Exchange Server Upgrade Option and Setup will start shortly
