Problem(Abstract)

When you upgrade IBM Rational ClearCase, Rational ClearQuest, Rational RequisitePro from version 7.1.0.x to version 7.1.1.x, 7.1.2.x, or 8.0.x.x, the registry key values from the 7.1.0.x version are not preserved and all values are reset to the defaut values for a new product installation.

Symptom

After upgrading from version 7.1.0.x to version 7.1.1.x, 7.1.2.x or 8.0.x.x, you notice that settings are reset to their default values.


Cause

During an upgrade, the installation process deletes and then re-creates part of the registry settings.

Resolving the problem

REGISTRY EDITS:

This solution contains information about modifying the system registry. Before making any modifications to the Microsoft Registry Editor, it is strongly recommended that you make a backup of the existing registry. For more information describing how to back up the registry, refer to Microsoft Knowledge Base article 256986


Before upgrading, back up the registry settings:

  1. Go to Start > Run.
  2. Type regedit.exe and press Enter.
  3. Locate the registry value to export. For example, HKLM\Software\Atria\ClearCase\CurrentVersion\Region
  4. Right-click on the key for the registry value. For example, HKLM\Software\Atria\ClearCase\CurrentVersion
  5. Select Export to export the registry key to a registry file. For example, clearcase_currentversion.reg
  6. Open the registry file.
  7. Delete the values you do not want to preserve.
  8. Repeat the export process for each registry key you want to preserve.
  9. After the upgrade, import the registry file (or files).

If you have already upgraded, you can reconfigure the registry values using the same method you had used previously to configure the registry values.

Table 1 lists the known configurable registry values that are overwritten when upgrading to 7.1.1.x, 7.1.2.x, or 8.0.x.x.
