Upgrade Notes for Otter 1.4

KB#1132: Last Updated Feb 13, 2019

Otter 1.4 is minor release with the following changes:

  • Agentless (PowerShell) Windows Communication (new feature)
  • Variable Enhancements
  • OtterScript/Execution Engine Changes
  • New API Endpoints

Upgrade Impact

Because most of the changes are additive, the upgrade risks are minimal.

Risk Mitigation

Because both variables and the execution engine have been updated, there is a potential for unintentional changes/bugs to be introduced. To mitigate these risks:

  • There are minor database schema changes, so make sure to back up your Otter instance in order to do a rollback.
  • Make sure that the installation's \Extensions directory is backed up prior to upgrade
  • Test configuration and orchestration plans in earlier environments prior to working against production servers

Upgrade Process

Otter may be upgraded by simply running the latest installer. The agents do not need to be updated.


Because there are database changes, a rollback will require uninstalling Otter, and then restoring your Otter instance.
