The correct answer is C. RIP must be installed in the source workspace. Relativity's Integration Points documentation states that to use Integration Points successfully, you must install the application to at least one workspace . In the specific context of promoting data between workspaces, Relativity also states that you are not required to have Integration Points installed on the destination workspace . That means the practical prerequisite is installation in the source workspace , not both source and destination.
This rules out the other choices. Integration Points is not described as an instance-level-only install requirement, so option A is incorrect. Option B is too broad because the destination workspace installation is explicitly not required. Option D is also incorrect because Integration Points is an application that must be installed in a workspace to be used. Therefore, for migrating documents from one workspace to another with RIP, the required prerequisite is that Integration Points be installed in the source workspace .
