Copy a NetApp volume to 3PAR

[RAJMEHTA1]

I would like to copy/migrate a NetApp volume to HP 3PAR.  What is the best way to do this with the least down time if at all?

What kind of data are we talking about?

Your most likely bet, is to look at host-based migration.

I have a bunch of volumes with SQL databases being hosted.  How do I go about doing host-based migration?

[radek_kubka · Accepted solution]

You present LUNs from both storage systems to the same host & use something like robocopy or xcopy to to move the content.

On the SQL side you detach database from the old LUN & attach it from the new LUN.

The main gotcha is to properly copy Windows ACLs, but this can be sorted using right switches with robocopy / xcopy.

That works!  Thanks.
