The tool is meant to migrate profiles with minimal modification, but its behavior can be altered by command line options.
Appendix G Using the Profile Migration Tool Installing the Profile Migration Tool • CB21AG and PI21AG client adapters have a limit of 16 profiles, so the total number of profiles that can be migrated is 16 minus the number of existing CB21AG and PI21AG profiles. If the number of profiles to migrate is greater than the number of profiles that can be migrated, some legacy profiles are not migrated. In this case, the client adapter priority is as follows, unless overridden by command line options: 1.
Appendix G Using the Profile Migration Tool Running the Profile Migration Tool Running the Profile Migration Tool Follow these steps to run the profile migration tool to migrate your 350 and CB20A profiles to CB21AG/PI21AG profiles. Note The best time to run the profile migration tool is immediately after the Install Wizard has installed the client adapter software.
Appendix G Using the Profile Migration Tool Command Line Options Command Line Options These command line options can be used to alter the behavior of the profile migration tool. The correct format is PMT -command. Note Leave a space between multiple commands (such as -command -command). • -AllowReRun—Enables the profile migration tool to be run multiple times. When you rerun the tool, it migrates all the existing profiles, even the ones that were already migrated.
Appendix G Using the Profile Migration Tool Command Line Options • -logfile —Enables you to change the name and location of the log file, which identifies the migrated and unmigrated profiles after you run the profile migration tool. The default name is migrate.log, and its default location is the system drive root (for example, C:). Examples: PMT -logfile logfile.log PMT -logfile C:\Cisco Aironet\migrate.
Appendix G Using the Profile Migration Tool Uninstalling the Profile Migration Tool Uninstalling the Profile Migration Tool The profile migration tool is uninstalled automatically when the client adapter software is uninstalled.
