parallel ghosted vectors

My code makes use of parallel ghosted vectors to transfer data between fluid and solid calculations. I am now trying to model large deformations in solid where the solid may cross several fluid subdomains. This essentially means that the entries for the parallel ghosted vectors would change their owning process. 

For instance, in case of 2 processes as shown below
Process  : Entries
0        : 0-n
1        : n+1-m

some entries (i,i+1....i+l) can move from process 0 to process 1 at some time t.

Is there a way to handled such parallel ghosted vectors without destroying the old and recreating a new parallel ghosted vector with updated entries?

Thank you
