That would work…or if a non-guaranteed migration is ok you can also just run vfiler migrate from the command line of the target system. When the mirror breaks it converts 32 to 64 though so check the burts that came out with that.

This just occurred to me - a plan forward to allow data motion and migration to 64 bit
I will test it asap, but basically its this since vfiler migration on 32bit -> 64bit aggrs is not possible,
destroy the 64 bit destination aggrs and recreate as 32 bit < 16Tb (leave off disks in execs of 16Tb)
datamotion vfilers 32->32 bit aggrs (supported)
add remaining disks to aggrs to trigger 64 bit background migration
this should accomplish the twin goals of evacuating prod cluster for the tray upgrades, and getting us onto 64bit aggrs without downtime…
thanks,
Fletcher.

Anyone know if its possible to force the in place 32->64bit aggr non-disruptive migration without having to add disk? I'm running into a 8.1R2 data motion issue where NMC is refusing to migrate vFilers from the 32 bit source cluster to the 64bit destination. The destination aggrs are at or above 16Tb so they need to be 64 bit
thanks
