How to extract backup data from 7.0 NB to 7.6 NB

I have two NB environments, with different version. Now I need to extract backup data from 7.0NB directly into 7.6NB, both are NFS based. Are there any commands / tools allow me to do that? If ...
7.1.x and Earlier

    1a) Create an NFS export somewhere, e.g. named "nbuxferA"

    1b) Create an NFS export somewhere, e.g. named "nbuxferB"

    2) Mount "nbuxferA" on masterA (7.0)

    3) Mount "nbuxferB" on masterB (7.6)

    4) On masterA create a Basic Disk storage unit pointing to the mounted export nbuxferA

    5) On masterB create a Basic Disk storage unit pointing to the mounted export nbuxferB

    6a) On masterA duplicate an image to stu-masterA-nbuxferA

    6b) Manually copy (not move) the files from "nbuxferA" to "nbuxferB"

    7a) On masterB do a phase 1 import of backup images from stu-masterB-nbuxferB

    7b) On masterB do a phase 2 import of backup images from stu-masterB-nbuxferB

    8) On masterB duplicate the images from stu-masterB-nbuxferB to some other storage unit

    9) On masterA expire the "copy number" of the copy of the image on stu-masterA-nbuxferA

    10) On masterB expire the "copy number" of the copy of the image on stu-masterB-nbuxferB

1a) Yes.

1b) Yes.

1c) You cannot use move because you need to later expire the copy on storage unit stu-masterA-nbuxferA.  i.e. you cannot make "backup data" disappear from NetBackup, because NetBackup has to manage the expiring and removal.   If you manually move/delete backup images without NetBackup knowing then the catalog could get in a mess with orphanned image headers which point to backup storage that no longer exists.

2a) There could be several methods available to you.  But without a detailed description of the NetBackup configuration of both environments, i.e. storage unit topology and storage unit connectivity and storage unit device types... then it is not possible for anyone to comment because we have no visibility of your NetBackup infrastructure.  If you were willing to supply exact OS versions and NetBackup versions of all master or master/media or media servers, and the storage unit details, then one of us might have been, and still might be, able to comment on other possible alternative backup data migration options.

2b) Maybe TSM can duplicate NetBackup images across low to higher (recent) NetBackup versions, but I've never heard of that.
