Checklist - Upgrading from Exchange 2007 to Exchange 2010

Exchange 2007 to Exchange 2010 migration is very frequent task going on in most of the organizations these days. The most important reasons for this server migration are enhanced and improved features of new Exchange 2010. After checking various surveys about same, I must say this new upgraded server has loads of amazing features for Exchange users. Few all new features of the Exchange 2010 are listed below –

  • This new Exchange version is 70 % more efficient than the old one in terms of disk read/write performance. Thus better disk performance circuitously will slow down the storage cost.
  • Exchange 2010 offers high Availability option for mailbox servers. Check more detailed feature description on  
  • One of the most eye catchy features of Exchange 2010 is the Voice mail Transcripts Preview. With this feature one can see the text-transcripts of voice mail.  
  • Native archiving is the feature which was lacking behind in Exchange 2007.  
  • Exchange 2010 also supports virtualization. Exchange virtualization is not just a cost cutter, 
  • reducing expenditure related to support staff, maintenance, power and space but it also improves business continuity. In case if the virtual machine goes down, computers can run on another virtual machine with no downtime server failure.  

There is no second thought that performing such server migrations are actually bit tough and time consuming but don’t worry we are here with a detailed checklist and tons of helpful resources those can help you in performing your Exchange 2007 to Exchange 2010 migration easily.  

Task 1 – Analyze your system hardware health; before moving to new server it is important to perform the disk subsystem health check. This step would help Exchange users in validating if the old hardware can take the load or not.  To perform this task the most recommended tool is to run JetStress on that machine

Task 2 – Run a system requirements test and update your system with system requirements of Exchange 2010.
