Migrating from 9.5 SP2 to 9.6 with Provisioning

Hello All,

We are looking to upgrade from 9.5 SP2 to 9.6. Has anyone upgraded to production yet,  and were there any issues with provisioning ?  I am looking for feedback on

1. Import/Export Templates from 9.5 to 9.6
2. PXE Rep installation and content replication
3. Provision template testing - any gotchas
4. HII Driver DB and driver isolation
5. Performance when imaging with the new 9.6 with multicasting technology
6. Any issues you encountered that would help us with the migration.

Thanks
