Migrating Data from one DFM 4.02 Instance to Another

I have a customer who has multiple DFM 4.02 installations worldwide and is looking to consolidate them. The issue that has come up is how do you migrate data from multiple instances of DFM 4.02 to one instance? We know about the following procedure which works for 1:1 migration but how would we do a 2:1 migration/consolidation?

  • Run the command: dfm backup create
  • This creates a backup file (.ndb format) which is stored in the <install_dir>\Netapp\DataFabric Manager\DFM\data folder.
  • Copy the .ndb file to the new server.
  • Run the command: dfm backup restore <backup file-name with location>

To take it to the next level there's a very real possibility that some partial consolidations may be involved as well. For example, customer has DFMA, DFMB and DFMC. They're looking to consolidate to DFMD and DFME; DFMA --> DFMD, DFMB --> DFME and half DFMC to DFMD and half DFMC to DFME. Is this possible?

Last question is if this would be possible in OC5.2?

Thanks in advance,

Jason

Hi Jason,

        Short answer is, its not possible. You cant merge 2 DFM into 1.

Long answer is, if you don't care about the history accumulated in DFMA for filer A, then you can discover filerA in DFMB, but you will not have the history of the same.

Also if it involves dataset, it makes it even more complicated to consolidate.

Thanks Adai. That's what I thought. So there's no command line option to dump an object (a filer) along with it's associated data to a flatfile for import to the other instance? Straight 4.02, no protection/provisioning manager.

Thanks,

Jason

There is no way to dump and import.
