You need to make a copy of the snapmirror volume on the new dr machine and then just tell netapp to use the new filer.
drfiler2> snapmirror initialize -S drfiler1:vol1 drfiler2:vol1 This creates a fast LAN copy of the volume on drfiler2 and it will contain baseline snapshots used by filer1 & drfiler1 drfiler2> snapmirror break vol1 drfiler2> snapmirror resync -S filer1:vol1 drfiler2:vol1 Break and re-establish the mirror from filer1. The resync will find the latest common snapshot, which should be what was copied from drfiler1, and then transfer just the delta. At this point, you can create the snapmirror.conf file on drfiler2 to keep the snapmirrors on a schedule.
There's also a bit of cleanup that you have to do, otherwise the baseline snapshot used between filer1 and drfiler1 will not be releasable (and will eventually run you out of disk space).
filer1> snapmirror release filer1:vol1 drfiler1:vol1
Good luck. Migration of snapmirrors is something that netapp does really well compared to other companies.

Hi,
We currently 3 filers, and are looking to move a snap mirrored volume to another filer, we would like to do this without having to recreate a new snapmirror and all the traffic associated with with it.
The example is:
Filer1 has Vol1 witch is snap mirrored to drfiler1 Vol1
We would like to copy/move Vol1 on drfiler1 to drfiler2, and continue with it being a snap mirror of Vol1 on Filer1, without having to reinitialise the snap mirror
Drfiler1 and Drfiler2 are both on the same site so we have no bandwidth restrictions.
Is this possible and could someone point me in the right direction of how to do it.
Thanks
Matt
