This article discusses how to handle SolarWinds Failover Engine installations when there are outstanding issues with other modules in the environment.
All FOE versions
In most cases, it is highly advised to resolve any outstanding issues with other modules before continuing with a Failover Engine installation. As in most cases, it is likely that the problem will be replicated to the secondary Failvoer Engine. Exceptions to this would include an issue solely with the Orion database, or other very specific exceptions. However, SolarWinds highly recommends you to inform your Solarwinds Support agent of any outstanding issues. They will be able to advise you whether the issue can be temporarily ignored or if the Failover Engine installation should be postponed.
