Before you run the migprofile.exe utility, verify that your legacy and destination environments satisfy specific prerequisites.
Run the migration utility on a physical computer or virtual machine that runs the destination Windows operating system version.
If you are migrating to a V5 user profile, run the utility on a Windows 10 machine.
If you are migrating to a V2 user profile, run the utility on a Windows 7, Windows 8 or 8.1, Windows Server 2008 R2, or Windows Server 2012 R2 machine.
Log in to the system as a local administrator.
Verify that the system on which you run the utility has network access to the CIFS network shares that contain the source path and destination path.
Verify that the user account that runs the utility is a local administrator on the destination CIFS network share.
If the user account that runs the utility does not have full ownership of the user profiles that are migrated, specify the /takeownership option with the utility.
This option passes ownership of the user profile folders to the utility during the migration. Ownership is returned to the users after the migration is completed.
Ensure that the users whose profiles are being migrated are not logged in to their legacy systems when you initiate the migration.
If a user is in an active session during the migration, the migration might fail.
Ensure that users do not start using their destination desktops before the migration is completed.
When users start using their Horizon 7 desktops, Horizon Persona Management creates destination V2 or V5 profiles for the users. If a destination profile already exists before the migration runs, the utility leaves the existing destination profile in place and does not migrate the legacy profile.
