Before you begin migrating NetBackup Snapshot Manager

Ensure that you complete the following before installing NetBackup Snapshot Manager:

Ensure that your environment meets system requirements.
See Meeting system requirements.
Create the instance on which you install NetBackup Snapshot Manager or prepare the physical host.
See Verifying that specific ports are open on the instance or physical host.
See Creating an instance or preparing the host to install NetBackup Snapshot Manager.
Prepare a RHEL 8.x or 9.x host for installation. You can either upgrade your existing RHEL 7.x OS to RHEL 8.x/9.x OS, or create a new system with RHEL 8.x/9.x .
- For upgrading the system from RHEL 7.x to RHEL 8.x or 9.x, follow the Red Hat documentation.
- For creating a new system with RHEL 8.x or 9.x, configure a Podman container platform
  See Installing container platform (Docker, Podman).
  The brief steps include:
  - Setup the RHEL repos
    For AWS cloud, enable the extra repos
    # sudo yum-config-manager --enable rhui-REGION-rhel-server-extras
  - Install Podman if required:
    # sudo yum install -y podman
Run the following commands to install the required packages (podman-plugins, lvm2, systemd-udev, udica, and policycoreutils-devel) on the hosts:
#yum install -y lvm2-<version>
#yum install -y lvm2-libs-<version>
#yum install -y systemd-udev-<version>
#yum install -y podman-plugins
#yum install -y udica policycoreutils-devel
Verify that specific ports are open on the instance or physical host.

Next, migrate NetBackup Snapshot Manager from the RHEL 7.x host to the newly prepared RHEL 8.x/9.x host.
