Would add the new fileserver to the current tracker ...
then set the devices that will be replaced to drain ... the tracker
should take care of replication to the new fileserver and clean the old
When that done you could easily shutdown the replaced fileserver.
then porting the db to the new db-server and tell tracker where to look
for db now.
