Examples described herein relate to migrating a virtualized execution environment from a first platform to a second platform while retaining use of namespace identifiers and permitting issuance of storage transactions by the virtualized execution environment. The first platform can include a first central processing unit or a first network interface. The second platform can include a central processing unit that is different that the first central processing unit and a network interface that is the same or different than the first network interface. The second platform can retain access permissions and target media format independent of one or more identifiers associated with the migrated virtualized execution environment at the second platform. Unperformed storage transactions can be migrated to the second platform for execution.
