Roll-back from Altiris ITMS 7.5 to Altiris 7.1

Hi,

We are planning to upgrade from ITMS 7.1 to Altiris 7.5.

When the ITMS upgrades to 7.5, the Symantec Agents on clients computers automatically contact the NS and automatically upgrade to 7.5. Please correct me if I am wrong.

Assuming that the above is true, and there is some issue with the upgrade or migration, we can rollback to the Altiris 7.1 on the NS. But what happens to the client agents? Can they downgrade themselves to 7.1 if a rollback is required.

Thanks
