ZFS - whole disk Vs slice

we have a ZFS file system that was created as a pool of just one disk (raid on a SAN) when this was created it was done as a whole disk, and so EFI label.

now we want to mount this file system into an LDOM.
my understanding of how ldom's and disk works this is that we can only do this as a slice.
the data looks to be all OK, but could this become an issue down the track?

so for example:

on the old server

zpool create testpool c0t600508A400070E320002200100170000d0
zpool export testpool

on the new server (control domain)

ldm add-vdiskserverdevice /dev/rdsk/c0t600508A400070E320002200100170000d0s0 volz@primary-vds0
ldm add-vdisk vdiskz volz@primary-vds0 ldom1

and then in the ldom (ldom1)

zpool import testpool

this is a 9TB file system , so we don't really want to have to copy all the data to a new 9TB file system.

From the ldm man page:

backend is the location where data of a virtual disk are stored. The backend can be a disk, 
a disk slice, a file, a volume (including ZFS, SVM, or VxVM), or any disk pseudo device. The disk label 
can be SMI VTOC, EFI, or no label at all. A backend appears in a guest domain either as a full disk or 
as single slice disk, depending on whether the slice option is set when the backend is exported from 
the service domain. When adding a device, the volume-name must be paired with the backend.

So I guess you can specify c0t600508A400070E320002200100170000d0 as backend.
