  • 1.  How to move WAS runing environment newly installed RHEL8

    Posted Wed May 17, 2023 05:00 PM
    Our production server currently running in old RHEL-6 and WAS version is 8.5

    Now we are planning to upgrade RHEL -8 but we don't want to upgrade our WAS.

    Can anyone suggest how to move existing WAS to newly installed RHEL8.

    Or share any documents for that

    There are migration documents in the Knowledge Center.  I usually do it a bit differently.  If this is NOT the DMGR then I install the product on the new system, create the profile with the same name, and then copy over the profile from the previous system.  After I run some wsadmin commands to update the hostname. This needs to be done for the new system and to the DMGR so the DMGR recognizes the Node is on a new hostname.

    If you are staying on WAS 8.5.5, you can use the backupConfig/restoreConfig commands to move configuration from the old system to the new system. 

    https://www.ibm.com/docs/en/was/8.5.5?topic=tools-backupconfig-command
    https://www.ibm.com/docs/en/was/8.5.5?topic=tools-restoreconfig-command

    If you had been working with WAS 9.0, clone migration and the -allowSameRelease option can be used to move systems at the same level, but this capability is not in WAS 8.5.5.

    If you want to keep the same version of WAS you can copy the file systems of WAS, Installation Manager, IMData (Data Location), IMShared, the home directory of the owner of the file systems, in case you did not install with admin option, or /etc/.ibm in case you install as admin.
    Then as Brian said you have to update the hostname in the node and dmgr (if you have one).

        As Brian asked you don't specified what is your environment (Standalone/ND) nor your WAS level.
        
        I have done in standalone environments.
        
        - Been in RHLE 6 update to 8.5.5 if you are not in this level at least to 8.5.5.3.
        - From WAS 8.5.5.3+ upgrade the system to RHLE 7.
        - Do tests of your environment.
        - Apply last WAS level mantenaince 8.5.5.23.
        - Upgrade to RHLE8.
        
        
        Hope this helps. Tell us if you need more support.

    Hi,

    I would like to add a small suggestion as I think you are more concerned about the Java upgrade rather than the WAS upgrade, I would advise to perform a backup/restore then upgrade to the latest fix that supports your java version (I guess 6). Also you can have a look at Transformation Advisor it can provide you an assessment on the complexity and effort for migration.

    Hope it helps.

    Good Luck
