Does FlexiCapture 12 support the Virtualization Failover instead of a Windows Failover cluster?
In theory, ABBYY FlexiCapture will work Virtualization Failover, but this is not a tested or recommended configuration.
Windows Failover Cluster operates services and monitors whether they are available. It is available for use with FlexiCapture 12 Processing Server and Licensing Server Windows Services.
Virtualization Failover operates servers, i.e., if one of the servers where the Processing Server and Licensing Server are installed stops, the Virtualization Failover activates another one. As mentioned above, this was not tested with FlexiCapture 12.
