Upgrading Exchange versions
Hyperion uses Quest Software Inc.'s Exchange Migration Wizard to move data from older versions of Exchange to Exchange 2003. Hyperion also used products from Houston-based BindView Corp. (which was acquired by Symantec last year) to help define and manage security policies, and to demonstrate compliance with new and evolving regulations.

"Microsoft has tools with native capabilities, but we would need four or five different Microsoft tools to do what Quest and BindView did," says Tiseo. The Microsoft tools worked at a lower level, he adds, and were more powerful, but less efficient to use.

Avanade's Rodgers recommends that his customers use external tools. "The external tool vendors like Quest and Binary Tree [Inc.] specialize in this kind of work and can do it with the least impact on users," he says. Avanade itself has built a tool for internal use that works in conjunction with Quest. Using the Avanade/Quest toolset, Avanade consultants have migrated as many as 1,250 users in a day, an extremely high volume that Rogers claims you "can only do with our automation."

Tools like those from Binary Tree, BindView and Quest can't migrate users as quickly because they may still require manual intervention at various points in the process. For example, "you will have to update proxies manually," says Rodgers. That limits the amount of users you can migrate at once. Hyperion migrated users in groups of 100, which

is considered a manageable number.

Hyperion also turned to third-party tools and managed services for spam and antivirus protection. "Prior to implementation, we wanted to minimize spam," says Tiseo. At that point, the company was dedicating 1.5 full-time employees just to monitor and manage incoming spam.

When he calculated what spam control was costing the company, Tiseo explored other options, primarily managed service providers. Eventually, Hyperion opted for FrontBridge Technologies Inc., which was subsequently acquired by Microsoft and became Microsoft Exchange Hosted Services. Hyperion is now blocking upwards of 18 million spam messages a month, which constitutes 98% of its spam.

For antivirus protection, the company turned to Symantec and Microsoft Antigen as part of a multilayered virus defense. It uses Symantec antivirus as a gateway and FrontBridge to scan for viruses. Antigen is used for local desktop scanning. "It has been so effective that we have been able to disable our junk mail filters," says Tiseo.
