The following topics describe how to run Control-M/Tape version in Test mode while running an earlier Control-M/Tape version in Production mode on the same CPU:
The following topic contains information about External Data Manager (EDM) support while running the two versions in parallel:
Note: The procedure described below is relevant only for the combination of newly installed Control‑M/Tape version and an earlier Control‑M/Tape version. For example, you can run one of the 9.x versions alongside an 8.0.xx version or an 8.0.xx version alongside a 7.0.xx version. Different instructions are provided for each prior version of Control‑M/Tape.
Working with your prior Control‑M/Tape version in Production mode while running the newly installed Control‑M/Tape version in Test mode enables you to test the new version as part of the upgrade process.
When two versions are working in parallel, output such as vaulting and retention management reports can be compared on a daily basis to ensure that new Control‑M/Tape version provides information that is consistent with the information provided by the earlier Control‑M/Tape version. Most of the new features supplied with the new Control‑M/Tape version can also be examined while working in parallel Test mode.
Throughout the test period, shutting down the new Control‑M/Tape version while the production Control‑M/Tape continues to operate can create differences in the Media Databases, making reports inconsistent. This sort of inconsistency may make it necessary to reconvert the production Media Database (in the earlier version) for use as a test Media Database (in the newly installed version).
To facilitate comparison of the output from the two systems, BMC recommends that both systems start with the same Media Database contents. Therefore, although it is not always necessary to stop the earlier Control‑M/Tape version to start the new version in parallel, BMC recommends that you stop tape processing before performing database conversion from the earlier version to the newly installed version.
When the testing period is over and you want to continue working with only version the newly installed Control‑M/Tape version, parallel execution support must be removed. The following paragraphs describe how to install and remove parallel execution support.
