Exchange 2010: To Migrate or to Stay Put
Cloud-based e-mail may be generating powerful market buzz, but in the enterprise, Microsoft Exchange today remains the dominant e-mail platform.
However, e-mail, though essential, is difficult and expensive to manage with its increasing storage requirements. So many businesses are now trying to untie e-mail from the rest of IT infrastructure elements such as storage, archiving and disaster recovery products, according to an independent survey by Osterman Research on Microsoft Exchange 2010 migration plans among enterprises with 1,000 or more users.
Consequently, making e-mail less dependent on the IT infrastructure will expand what e-mail should include -- and businesses are demanding that e-mail encompass features like archiving and unified communications.
All of this sets the tone for the adoption -- or lack thereof -- of Exchange 2010, which has new features that include: built-in e-mail archiving that eliminates for a third-party archiving vendor; the ability to use cheaper storage systems; voicemail and other unified messaging tools rolled into Outlook; and an enhanced user experience in both Outlook and Outlook Web Access.
Exchange 2010 has more momentum now than Exchange 2007 had at a similar time in its lifecycle, according to the Osterman Report, which predicts that Exchange will remain the market leader for at least the next several years.

The Osterman Research survey also reports that 44% of respondents say they plan to migrate to the new e-mail platform within the next 18 months, which is unusually high for a new Microsoft product, according to the report.
However, migrating to Exchange 2010 will be challenging, confusing or just plain not feasible in a soft economy that has forced companies to cut back or freeze IT budgets, according to the report. As the economy starts to improve, enterprises will have to decide whether they have room in their budgets, or the staff to invest in an Exchange 2010 migration.
Here are six reasons driving enterprises to move to Exchange 2010, and six reasons they are putting it off for now, based on the Osterman survey data.
