Preparing for Installation › Concurrent Releases

Concurrent Releases

You can install this release of CA Disk and continue to use an older release for your production environment. If you plan to continue to run a previous release, consider the following points:

• When installing into an existing SMP/E environment, this installation deletes previous releases. The libraries and DDDEFs from the previous release may be deleted after this release has been accepted in SMP/E.
• If you acquired your product from tape or with Pax-Enhanced ESD, select different target and distribution zones for your new release from where your current release is installed. The new zones use different libraries than your current release.

  Note: CA MSM installs into a new CSI by default.

• Define DDDEF entries in your new zones to point SMP/E to the proper libraries for installation. Ensure that they point to the new release libraries.
