Lost my H5 licentie when updated to H6?

Still not quite sure what is actually happening here with the Halion 5 licence and software

1: Is Halion 5 automatically deleted and replaced by the Halion 6 update install?

2: Is the Halion 5 licence removed from the USB dongle after authorisation or is it just supplemented with a Halion 6 licences as well.

If the licence is deleted from the dongle there is no way to run my existing Halion 5 on my 32bit machine.

Can someone clarify the USB dongle position.


Thanks

David
