    Hi,

    The following is a link from the ClearCase 8.0 infocenter for installing and upgrading ClearCase.

    There are subtopics below this link with more details.

    I hope this helps.

    Hello Jones,

    I understand that you are looking at information for planning your ClearCase upgrade activity.
    Couple of things that you have to make sure to look into are:

    1. The Hardware and the Software requirements for your Operating system
    The below link has the System requirements details:

    http://publib.boulder.ibm.com/infocenter/prodguid/v1r0/clarity-reports/report/html/softwareReqsForProduct?deliverableId=1316006977787&osPlatform=Linux

    2. General information about ClearCase 8.0.x release:

    http://www-01.ibm.com/support/docview.wss?uid=swg24035146

    3. Overview of planning your upgrade:

    http://pic.dhe.ibm.com/infocenter/cchelp/v8m0r1/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_ms_install.doc%2Ftopics%2Fc_planning_upgrade.htm

    4. Upgrading with the Installation manager:

    http://pic.dhe.ibm.com/infocenter/cchelp/v8m0r1/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_ms_install.doc%2Ftopics%2Fc_upgrading.htm

    5. Configuring the environment after the Upgrade:

    http://pic.dhe.ibm.com/infocenter/cchelp/v8m0r1/index.jsp?topic=%2Fcom.ibm.rational.clearcase.cc_ms_install.doc%2Ftopics%2Fc_post_upgrade_config.htm

    Following are some additional points that you need to think before the upgrade:

    1. Have you thought and worked on taking back ups of the critical ClearCase data for the upgrade
    2. Is the Upgrade being performed on a new machine or an existing machine which is having ClearCase 7.1.2.x currently installed
    3. Are you looking at upgrading the VOB schema versions to Schema 80 ?
    4. Are you looking at upgrading the feature level ?
    5. Is it a multisited set up? If yes are you planning to upgrade all the sites to 8.0.x or not ? - This is important because the VOB's newly created in the CC 8.0.x will be of feature level 8 and will not be compatible with the clients/ servers of older ClearCase (7.1.2.x) versions.
    6. What is your plan about upgrading the clients, would you still have some clients of older ClearCase versions.

    Following is the compatibility matrix :

    http://www-01.ibm.com/support/docview.wss?uid=swg21597061


    7. Have you planned about upgrading the license server as ClearCase 8.0.1 needs the latest license server

    Please note that the upgrade activity will be a project by-itself.
    I suggest you to do a proper planning and try a test upgrade on one of your test machines.

    Hope these details helps you in giving some insight about the planning of the Upgrade as such.

     

    Thanks,

      Thanks for your information.

        I would use the existing machine which to upgrade from 7.1.2. to CleaeCase 8.0.x , and would like to upgrade the feature level and license server also. May I ask more question of the upgrade ?

     Firistly, Before upgrade that i backup the critical ClearCase data,  and uninstall ClearCase 7.1.2., goto install ClearCase 8.0.X , and then , Am i need to register the VOB(s) ??  Please advise.

    Hello Jones,

    Good day.

    Yes, you are right.
    After installing ClearCase 8.x, you need to register all your VOB's and View's.
    Schedule your Job's/ Schedulers, apply any triggers that were applied in your old CC setup.
    So its important to backup all these CC data like: VOB/ VIEW storage, Trigger scripts, Scheduler and the Jobs data.
    You need to go through the link that I previously shared that talks about the critical data to back up before upgrade to know all the important things that is to be backed up.

    Thanks,

    Avinash S

    if you are updating ClearCase from 7.1.2 to 8.0.x on the registry server, assuming that you are not changing any settings (registry region, license settings, etc.) It should pick it up without much if any user intervention...

    When you uninstall Clearcase from a Windows host, your settings are saved in C:\ProgramData\IBM\Rational.preserve (there is a mapping directory on unix as well) that will contain a number of directories. if you reinstall, the settings from the prior release will be reapplied. Whether you want them or not, actually.

    If you want to be especially careful and save your key Clearcase data yourself, you can copy these directories out before doing the upgrade:

    Windows:

    • {CC Install directory}\config\magic (if you modified the standard magic file)
    • {CC Install directory}\config\scheduler\tasks (if you modified the default job files, which you shouldn't do in this dir.)
    • {CC Install directory}\config\services (this shouldn't have been modified in here, but just in case)
    • {CC Install directory}\config\vob
    • {CC Install directory}\var\ccweb (if this is a web server and you left it at the defaults)
    • {CC Install directory}\var\config (which is where most of the config modifications should be)
    • {CC Install directory}\var\log (optional: if you want to keep server logs, etc)
    • {CC Install directory}\var\rgy
    • {CC Install directory}\var\scheduler
    • {CC Install directory}\var\shipping
    • Export the HKEY_LOCALMACHINE\Software[\Wow6432Node]\Atria\Clearcase key.

    Unix:

    • {CC Install directory}/config/magic (if you modified the standard magic file)
    • {CC Install directory}/config/scheduler/tasks (if you modified the default job files, which you shouldn't do in this dir.)
    • {CC Install directory}/config/services (this shouldn't have been modified in here, but just in case)
    • {CC Install directory}/config/vob (especially if you set non-default lock manager parameters as they WILL be reset)
    • /var/adm/rational/clearcase/ccweb (if this is a web server and you left it at the defaults)
    • /var/adm/rational/clearcase/config (which is where most of the config modifications should be)
    • /var/adm/rational/clearcase/log (optional: if you want to keep server logs, etc)
    • /var/adm/rational/clearcase/rgy
    • /var/adm/rational/clearcase/scheduler
    • /var/adm/rational/clearcase/shipping
