Initial version for an admin utility for migration of a project from V to T This code will first dump all the objects to a file, so the data will not be lost. Then it will delete each object using the V plugin, move the project to the T plugin and recreate each object. Usage: nsxadmin -r projects -o nsx-migrate-v-v3 --property project-id=<V project to be migrated> --property external-net=<T external network to be used> Change-Id: I816b63f40ada945d321db4566224f8a964a39a8f
