Rolling upgrade from InfoScale 7.4.1 to 8.0 gets stuck during phase 1 (4037913)

A rolling upgrade from InfoScale 7.4.1 to 8.0 gets stuck during phase 1 at the poststart operation. This issue occurs due to a lower cluster protocol version on the existing cluster.

Workaround: Upgrade InfoScale to 7.4.1 Update 5 first, and then perform the rolling upgrade to InfoScale 8.0.
