Vfiler migration complete and snapmirror relations

HI All,

I succesfully start vfiler migration of my Vfiler <X> from Filer A to Filer B, Vfiler<X> got 10 volumes.

5 volumes of Vfiler <X> from Filer A are snapmirrored to Filer C (Destination) another site.

First question Vfiler migration complete will work in this enviroment or I have to break and delete the relation to Filer C.

I don't want to do another Full Basecopy of that 5 volume after complete to Filer C too much TB...

If before to Complete migration I update and quiesce the 5 volume from Filer C and after complete I update snapmirror.conf with new source Filer B:Vfielr <X> resume will work ?

Filer are all Ontap 8.2.3 7-mode.

Thanks.
