I'm upgrading from CA InterTest Batch 8.5. What is the minimum CARS level for CA InterTest Batch 10.0?
In terms of "what's new" for V10:

In terms of a migration consideration from 8.5 to 10.0, in regards to the PROTSYM dataset:

Downloading only the CARS is not downloading the fixes. CARS txt files are in fact only text files stating what are all the PTFs for that current recommended service period.
You will also need to download manually the PTFs from CSO. Check out this document:

This is the CA main page with all additional info:

There is no recommended MINIMUM cars level. The recommendation is to be current on maintenance which is CARS1707 right now. By applying all the available fixes you will not run into any problems previously fixed by the published maintenance.
Intertest 10.0 base was published December 2016. So CARS levels below CARS1612 are not relevant.
