Upgrading Existing Objects
In order to upgrade the existing objects with 1.1.0 (i.e 1.0.1 → 1.1.0 or 1.0.2 → 1.1.0), just after the upgrade, it is mandatory to update below two parameters of dSource using the "custom Configuration" option on the UI :
- Source IP Address
- Source Port
A critical fault will show up on dSource just after the upgrade. It is because the engine is not able to find the source config from which dSource was created. As we have moved to manual discovery in this release, we need to mark this fault as resolved on the status tab of dSource.
