Following best practices ensures the success of a profile migration.
In Horizon 7, configure the destination desktop pools for your users before you begin the profile migration. Configure Horizon Persona Management for the desktop pools.
In particular, configure a CIFS network share as the Horizon Persona Management remote profile repository. The CIFS network share will be the destination path in the migration.
If you are migrating V1 profiles on legacy Windows XP machines, run the migration utility on a Windows 7 or later 32-bit system, because most V1 profiles are 32-bit.
If you can, run the migration utility on the same template or virtual machine image that the destination Horizon 7 desktop pool will use. Folders and files in the base image's default profile are then migrated to the destination user profiles.
If a user must continue to use the legacy system after a migration, configure redirected folders for both the legacy system and the destination Horizon 7 machine. This approach allows the user to access files from both systems.
