Is your data on the heterogeneous storage SAN, NAS or mixed?

You have to go application by appication. It all depends on the amount of data and downtime allownce you have.

  • For some applications it may be feasible to bring down the application, move data to netapp and start the application from the netapp. You could do a backup/restore. Simplest but large downtime.
  • For other cases you can have both storages visible to the server and setup a robocopy /mr to slowly copy data to the netapp. Then bring down the application, do a final robocopy /mr and bring up the application from the netapp. This could give a smaller downtime.
  • For databases in general you have large files and you could use logical or application replication from inside your application.
  • There is software doing this, but in general it is expensive. This could give a smaller downtime.
  • You can use hardware solutions, like SAN "replicators/redirectors", much more expensive, but gives the smallest downtime. There was a company called Reldata doing this, then bought by Starboard, not sure what they are doing now.
  • NetApp used to have an excellent software for this, called Topio, first OEM, then bought the company in 2006, in 2007 redesigned and enhanced it as ReplicatorX (http://www.netapp.com/us/company/news/news_rel_20070405.html) and then suddendly discontinuing it shortly being announced, probably because of the then crisis and cuts. The excuse was that there was not a considerable market for it!
