1. A system comprising: (i) a first information management system comprising: a first storage manager, comprising one or more processors and computer-readable memory, configured for managing the first information management system, a data storage device comprising a secondary copy of data that originated in the first information management system, and a first computing device associated with the data storage device; (ii) a second information management system comprising: a second storage manager, comprising one or more processors and computer-readable memory, configured for managing the second information management system, and a second computing device comprising: (a) a first executable version of an information management software, and (b) a second executable version of the information management software, and (c) shared binaries for instantiating the first executable version of the information management software and the second executable version of the information management software; wherein the second storage manager is further configured to: (A) manage storage operations for data generated by the second computing device executing the second executable version of the information management software, and (B) instruct the second computing device to execute, based on the shared binaries, the first executable version of the information management software to receive data from the first storage management system, and (C) transmit to the first storage manager information about the second computing device; wherein the first storage manager is further configured to, based on the information about the second computing device received from the second storage manager, manage a data transfer of the secondary copy of data to the second computing device executing the first executable version of the information management software; wherein the first storage manager lacks an ability to manage storage operations for data generated by the second computing device; and wherein after the data transfer is completed, at least one of: (I) the first storage manager is further configured to communicatively decouple the second computing device from the first computing device, and (II) the second storage manager is further configured to instruct the second computing device to stop executing the first executable version of the information management software.
