Storage options for OS upgrade

Hello,   we have a NetBackup 10.4 server that we need to upgrade the OS from rhel 7 to rhel 9. Currently the MSDP is on the same disk that the OS will target (/dev/sda) so I need to copy/relocate the backup images during the upgrade.  I opened a case with support and they suggested mounting SAN storage.   Is this the only option to duplicate the backup data, or can we use DAS/NFS for setting up a new AdvDisk?  This particular host has no other drives in it to relocate the data to, so it will need to be off the host during upgrade.  
Thank you

    If this will be used only for storing NetBackup data (NBU and dedup) to have a backup during the upgrade, without running backups, then both options are acceptable. However, I would go with DAS as it will provide better speed.

    there is no need to setup an advanced disk.

      Yes, it is only to move "/backup" out of the path of destruction during the loading of the new OS.  Not for backup jobs to run. - Support informed me the server can only have one MSDP pool on it,  so wondering if we can just move it to another storage (NFS/DAS) - then move it back to the local disk after the upgrade and DR recovery process is completed.

        yes, this is the way to go.  
        you do not need to have a second msdp pool. just use "cp -av" or any other sync software to copy the data.  if you delete the original folder be sure that all data are copied.
        copy the /usr/openv folder as well,, just to have a backup of the entire netbackup installation.

        and pay attention to for mount points or links you may have inside netbackup or msdp folders
