After testing we disabled the Qos Blade from the firewall and&nbsp; couple days later we enabled Qos Blade back. Need to revert the old rules of Qos&nbsp; 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.</P> Sat, 18 May 2019 11:02:20 GMT https://community.checkpoint.com/t5/General-Topics/Installation-History-Qos/m-p/53759#M10739 sajin 2019-05-18T11:02:20Z https://community.checkpoint.com/t5/General-Topics/Installation-History-Qos/m-p/53763#M10741 While you can install a previously installed policy, you cannot roll back the entire configuration database to that point.<BR />This limitation is not specific to QoS.<BR />Refer to: <A href="https://community.checkpoint.com/t5/Policy-Management/How-to-revert-a-Policy-or-discard-changes/m-p/3242" target="_blank">https://community.checkpoint.com/t5/Policy-Management/How-to-revert-a-Policy-or-discard-changes/m-p/3242</A> Sat, 18 May 2019 16:23:30 GMT https://community.checkpoint.com/t5/General-Topics/Installation-History-Qos/m-p/53763#M10741 PhoneBoy 2019-05-18T16:23:30Z
