Applies to: <\/strong>Ephesoft Transact 2020.1 on Linux<\/p>\n

This article provides information on the two-part process of how to update your version of Red Hat Enterprise Linux to a supported previous release. Refer to Platform Configuration and Third-Party Integrations 2020.1<\/a> for more information on supported environments.<\/p>\n

Note: <\/strong>Ephesoft Transact 2020.1 only supports RHEL 7.5 and 7.6.<\/p>\n

Prerequisites<\/h2>\n
    \n
  1. You must have a fresh server of RHEL.<\/li>\n
  2. You must be a root user.<\/li>\n<\/ol>\n

    Note<\/strong>: If you are not the root user, execute the following command:<\/p>\n

    sudo su root<\/pre>\n
    Upgrade to Current Release<\/h2>\n
    Perform these steps to upgrade to the latest version of RHEL. These instructions refer to RHEL 7.7 as the latest version.<\/p>\n
      \n
    1. Verify your Linux kernel version:<\/li>\n<\/ol>\n
      uname -r<\/pre>\n
      Sample output for RHEL 7.3:<\/p>\n
      3.10.0-514.21.2.el7.x86_64<\/pre>\n
        \n
      1. Update all packages with available updates:<\/li>\n<\/ol>\n
        yum update<\/pre>\n
          \n
        1. Reboot the server to complete the upgrade:<\/li>\n<\/ol>\n
          reboot<\/pre>\n
          Note<\/strong>: You will be logged out upon reboot. Log back in to continue.<\/p>\n
            \n
          1. Verify your updated Linux kernel version:<\/li>\n<\/ol>\n
            uname -r<\/pre>\n
            Sample output for RHEL 7.7:<\/p>\n
            3.10.0-1062.9.1.el7x86_64<\/pre>\n
            Downgrade to Supported Release<\/h2>\n
              \n
            1. Downgrade to an earlier version of RHEL:<\/li>\n<\/ol>\n
              yum downgrade redhat-release<\/pre>\n
              Note<\/strong>: This will downgrade by one release version of RHEL. For example, if your current distribution is RHEL 7.7, it will take you to RHEL 7.6.<\/p>\n
                \n
              1. Reboot the server to complete the downgrade:<\/li>\n<\/ol>\n
                reboot<\/pre>\n
                Note<\/strong>: You will be logged out upon reboot. Log back in to continue.<\/p>\n
                  \n
                1. Verify the updated Linux kernel version:<\/li>\n<\/ol>\n
                  uname -r<\/pre>\n
                  Sample output for RHEL 7.6:<\/p>\n
                  3.10.0-957.el7.86_64<\/pre>\n
                  Note: <\/strong>If your kernel downgrade fails when downgrading to RHEL 7.6, repeat steps 5-7 to downgrade again to RHEL 7.5.<\/p>\n
                    \n
                  1. Install the kernel version required to run RHEL 7.5 or 7.6:<\/li>\n<\/ol>\n
                    yum install <kernel version><\/em><\/strong><\/pre>\n
                    Note<\/strong>: Check for the latest stable kernel version from Red Hat before upgrading. The following is an example command for RHEL 7.6:<\/p>\n
                    yum install kernel-3.10.0-957.el7<\/pre>\n
                      \n
                    1. Reboot the server to complete the download:<\/li>\n<\/ol>\n
                      reboot<\/pre>\n
                        \n
                      1. Verify your Linux version:<\/li>\n<\/ol>\n
                        cat \/etc\/redhat-release<\/pre>\n
                          \n
                        1. Verify your Linux kernel version:<\/li>\n<\/ol>\n
                          uname -r<\/pre>\n
                          You have successfully updated your Linux distribution to a supported previous version.<\/p>\n","protected":false},"excerpt":{"rendered":"
