Installation History Qos

[sajin]

Qos Blade was enabled in Firewall R80.10 and few Rules was created in smart dashboard of Qos. After testing we disabled the Qos Blade from the firewall and  couple days later we enabled Qos Blade back. Need to revert the old rules of Qos  and in the Installation History we reverted to the old policy package. The Qos policy is not reverting but the VIEW option of the Installed package shows the old configuration in READ ONLY MODE. Need to know whether the Installation History will not support Qos.

While you can install a previously installed policy, you cannot roll back the entire configuration database to that point.
This limitation is not specific to QoS.
