Blackberry PROFESSIONAL SOFTWARE FOR MICROSOFT EXCHANGE - - MIGRATION GUIDE Manual page 6

Migration Guide
The setup application runs a preinstallation tool that verifies that your environment meets the minimum system requirements
for the BlackBerry Professional Software. The tool displays the results of the analysis on the screen. It also writes the results
in the log files in the following location: <drive>:\Program Files\Research In Motion\Blackberry Enterprise Server\logs
\installer. The file names begin with DetectionLog_ .
If components of your existing BlackBerry small business solution, such as the BlackBerry Router or the BlackBerry
Attachment Service, are currently installed on separate computers, the components remain installed, but the BlackBerry
Professional Software ignores them and uses the components that the setup application installs during the migration process.
By default, the BlackBerry Professional Software uses the CAL key from your existing BlackBerry small business solution. If
you have a new CAL key, you can replace the existing CAL key after the installation.
