Hyland Software recommends that customers run an entire installation on the same version of OnBase. Doing so ensures that the OnBase solution is easier to support, troubleshoot, and maintain. Occasionally, complex upgrade scenarios require a customer to run in a mixed version environment for a period of time. While this is an acceptable short term solution, Hyland Software recommends that organizations strive to eventually complete an upgrade of their entire OnBase solution. For customers that require a mixed version environment during an upgrade, your first line of support should be contacted to provide expert guidance.
If, during an upgrade, an organization finds itself with a critical problem, Hyland Software should be contacted prior to any attempt to roll back an upgrade. Under no circumstances should users or OnBase solution providers set back or change the database version field (even if this has been done in the past).
The current version of the OnBase Configuration module should be used under all circumstances.
For more information on upgrading, see the Mitigating Risk in Upgrades document, located in the Resources section of the OnBase Upgrades Technical Community on the Hyland Community site.
