Upgrade from DP 7.03 to 9.02 - Migration of DCBF and filenames

Hello,

Before I start to upgrade my PRD backup server, I set up a sandbox (backup/restore IDB) to check if everything works during the upgrade process. 

- installed DP 7.03 (same patch level)

- restored the IDB

- checked IDB (omnidbcheck -extended, omnidbcheck -bf, omnidbcheck -dc)

- install DP 9 (auto upgrade process)

- checked IDB

- installed DP9.03 patch bundle

- checked IDB

In the installation guide of DP 9 I found the part of (Migrating the Detail Catalog Binary Files (DCBF)).

- report of the old catalogs (omnimigrate.pl -report_old_catalog):

Old Detail Catalog Binary Files size:

DCBF ( 692 files):                 4085 MB
Old filename data files:           5434 MB
Total:                             9519 MB

- start migration of the old entries (omnimigrate.pl -start_catalog_migration) (runs 12h):

Migrating catalog of the medium 33014e0a:54cd5e8a:0aa8:029c (692 of 692).

Done!

D:\Program Files\OmniBack\bin>perl.exe omnimigrate.pl -report_old_catalog

Old Detail Catalog Binary Files size:

DCBF (   0 files):                    0 MB
Old filename data files:           5434 MB
Total:                             5434 MB

That's it, nothing more in the guide what to do with the old filenames.

I start searching the web and found some posts, a very good one by Daniel Braun (http://www.data-protector.org/wordpress/2014/03/migrate-dp-8-xx-dp-8-xx-hardware-ms-windows-operating-system/) which just describes a release change of the OS or the HW, but with the same steps .. well it's german ..

He said, if some old filename files still exists, copy them to the new db80 path and run the following reports:

- omnidbutil -remap_dcdir

-omnidbutil -fixmpos

Can someone explain if I have to do this step and if yes, where do I have to move the old db40 filename files exactly?

And, do I missed something else?

Thanks for any help!

Best regards,

Tobias
