1. you can check under Settings |History if the infos there are sufficient for you.
2. if the inventory item in the inventory is untouched the newly installed asset with an agent will take over (this is also working over different OS, so if you reuse an old Windows Workstation as Linux file server for a branch office or similar) If you delete the inventory item a new asset is created
3. if the inventory item is not deleted it keeps all tickets etc after the reinstallation

1) Is there a way of tracking and reporting which user has been allocated what asset, and maintaining a history within KACE SMA?

Assets can be assigned to a user and this is kept in the asset's history. Depending on the history retention settings this may or may not be adequate, depending on how frequently asset assignment changes. 

2) If an asset is wiped and re-installed or upgraded, will KACE SMA recognise it as the same asset, or re-enroll it as  a new asset?

This depends on the SMA configuration. Our SMA is configured to match inventory records with asset records based on the serial number, so when we wipe a device it associates with the same asset. Others have their SMA configured to match an asset to the inventory based on machine name, in which case it might not match the previous asset (depending on your naming scheme).

3) If KACE SMA  recognises the asset after a re-installation, will existing Service Desk tickets remain allocated to that asset so staff can refer to its incident history?

Tickets can be associated with both assets and inventory, so that depends on your configuration (how machine inventory and assets are related), which thing you associate (the asset or the machine), etc. Also, by default the service desk will try to associate the user with a primary machine and assign that machine to the ticket. You could use a custom ticket rule to either change that value or set the asset field based on that machine, or even create a custom field and store information there.

For a user to be assigned as the owner of an asset that is not a Device i.e. an asset record not linked to an agent device, you will need to add a User field into the Asset Type so that the user can be recorded in the asset record.

In the Asset record you will then get a populated dropdown of user accoounts on the SMA

And you will also be able to see the assigned assets of all types in the User records

The ownership data can then also be updated and managed from within mobile asset scanning apps such as the Go app or BarKode
