Users would not be allowed to configure these parameters for PRIME & FOUNDATION Compliance Suite.
In addition, during the upgrade, prior configured values would be removed and would be configured with default values as per standards.
Workaround:
To work around this issue, In version 6.4.5, you may configure values as ikelifetime=86400 and salifetime=28800 in local extensions for these two Compliance Suite hence you would not find any change during an upgrade.
