Seeding an ONTAP 8.3 to 8.2.3 SnapVault using SMTAPE

Note: This does not work but the post is still useful to show why it doesn’t work (“backup image header version is not supported”).

Carrying on from the previous post....

In this post we go:

NACLU7:NASV1 -> SMTAPE BACKUP -> Staging disk
8.3          -> SMTAPE BACKUP

Staging disk -> SMTAPE RESTORE -> NACLU5:CIFSV1
             -> SMTAPE RESTORE -> 8.2.3

NACLU7:NASV1 -> SV (RESYNC) -> NACLU5:CIFSV1
8.3          -> SV (RESYNC) -> 8.2.3

Seeding and ONTAP 8.3 to 8.2.3 SnapVault using SMTAPE - Step-by-Step Walkthrough

N.B.: Cluster and Vserver peers are already created from previous posts.

Now we copy the image from NACLU7’s \\NASV1\SVVOL01_STAGING$ to NACLU5’s \\CIFSV1\SVVOL01_STAGING$ staging volume (perhaps via a generic and transportable disk storage device.)
