As long as you can mount the sparse file on Dom0 then it's trivial - 
just mount the source and destination volumes, and copy the files 
across. My preferred method is rsync, but there are plenty of options.
For rsync, the syntax would be "rsync -avH --numeric-ids /source/ /dest/"

You can convert mountpoints as well this way, eg if you previously 
had /home as a separate volume and want to combine it with /, then 
just mount all the volumes are required before doing the copy. Eg, 
mount the source / on /source, and the source /home on /source/home.
If you can't mount the source volume(s) on Dom0, then add the 
destination volume to DomU and copy the files there.
In either case, you are simply sizing the new volumes as you make 
them and putting the file on later.
