It is very rare. Last year SGVO was very loaded compared with Auvo. And their intention was to clear all backlog by 2013. So Auvo helped Sgvo for that purpose and some file were transferred (like from mid Dec-11 to mid Feb-12 for MI-3 And some for MI-2) to Auvo.
Once any file is transferred to another VO, u can know it by mail or from MR mail.
If u want to land another state no problem. Suppose, KLMY Bhai mentioned his destination to Toronto but he will land Calgary (May be). So, dont be tensed.
Thanks ...............
