1. A method for improving performance of a system using shared storage comprising: determining a unit of shared storage associated with a computing environment to be migrated from a source computing platform, the unit of shared storage utilized by the source computing platform; identifying, using at least one computer processor of the system, a storage management memory structure of the source computing platform associated with the unit of shared storage, wherein the storage management memory structure improves performance for the environment to be migrated; retrieving, using the computer processor, the storage management memory structure of the source computing platform for the unit of the shared storage; transferring the storage management memory structure to a target computing platform; and building a portion of storage management memory for the target computing platform utilizing the transferred storage management memory structure, wherein building the portion of storage management memory for the target computing platform improves performance for the environment after migration of the environment to the target computing platform, wherein building the portion of storage management memory reduces a need to rebuild storage management memory on the target computing platform utilizing disk reads, and wherein the transfer of the storage management memory structure and the building of the portion of storage management memory for the target computing platform occur during migration of the computing environment prior to a resumption of one or more environment processes at the target computer platform.
