Restrictions for rolling back

Files that are migrated with one version of the HSM for Windows™ client might not be compatible with other versions of the HSM for Windows client.

After IBM® Storage Protect HSM for Windows version 8.1 is installed and in use, do not roll back to an earlier version or to a fix-pack earlier than version 7.1.6.

Stub files that are created with version 8.1 and higher are not compatible with versions earlier than 7.1.6. versions earlier than fix-pack 7.1.6 of the HSM for Windows client cannot recall files from stubs that are created with version 8.1 or version 7.1.6 and later versions.
