Back up environment resources

When upgrading DevOps Code ClearCase®, back up critical resources before you begin the upgrade. These back up files can help you recover any information, files, or configurations that might be lost or corrupted during the upgrade.

Back up the following types of resources before upgrading.
  • VOBs
  • Registry directory and client list
  • Tasks subdirectory of the scheduler directory (scheduler/tasks)

    Do not back up or copy the db file. It cannot be preserved across release upgrades and will be regenerated automatically the first time the scheduler runs after the upgrade.

  • Shipping directory
  • Any custom job scripts
  • The albd.conf file that specifies the albd_server configuration.

    If you are upgrading from ClearCase version 7.x to version 8.x, you cannot use the version 7.x albd.conf file with ClearCase version 8.x because the file formats are incompatible. If you are upgrading to ClearCase version 8.0.x or porting configuration files from ClearCase version 7.1.2, use the default albd.conf file that gets created when ClearCase version 8.x is installed or reinstall ClearCase. See technote 211585.

  • The vob_scrubbers_params template

    The vob_scrubber_params template changed in ClearCase version 8.0.1. If you have customized the file, back up the file in another directory. After the upgrade, merge the customized settings into the version 8.0.1 file.

See Backing up critical DevOps Code ClearCase data for information about creating back ups.
The following table provides the default directory paths to the resources to preserve. All paths use ccase-home-dir for the default ClearCase installation directory:
  • Windows: ccase-home-dir is C:\Program Files\DevOps\Code\ClearCase\\\
  • Linux and UNIX: /opt/devops/code/clearcase
