problem to move linked clone desktop/pool to new datastore

Hi,

I have got a problem in View 5.1.1

When I try to move my linked clone desktop/pool to a new datastore in this steps,

1) add new Datastore(s) to the pool

2.) unselect the old one

3.) recompose pool -> VMs will be migrate to the new datastores

my problem is that something resides on the old datastore.

In "desktops" under "datastore" there is the old and the new datastore used?!?

During the migration I can see a failure "delete file  file [datastore1] Test1/sdd not found" in the statusbar of vSphere Client

Whats going on there? Is there a workaround? Any idea?

Thanks, gig
