Older version cannot be upgraded directly to some of the newer code versions. As Colin suggests, upgrading the controller to 6.1.3.6 again should resolve your issue. For future upgrades, refer to the following guidelines (each release notes version covers the requirements).
You can directly upgrade from
- 6.0.1.x or later
- 5.0.3.1 or later
- 3.4.4.1 or later
