No, not if you don't use all drive on the old HD in parallel.

LVM can hide volumes from OS2. So go on and mount both disks on the 
SCSI bus.

Then, when we now will assume that your old drive is not LVM aware yet 
you'll see
- OLD drive:  no volume yet - so no drive letter assigned to it
- NEW drive:  no volume yet as it is really epmty (its new)

So you fires up LVM that shows you the physical drives only.

Make the partitons and volumes on the NEW drive as you likes it to 
have. That means you may now have used up all the drive letters from 
C: to P: on the new drive.

Now you fires up LVM again and goes the following steps on the OLD drive:
- create a volume from existent partiton
- this requires that you assign a drive letter to that volume.
   This is fine as you may no assign the drive letter X: to the volume
   that was ordidary G:
- copy the content of X: onto the new G:
- back into LVM and hide X: from eCS. That does nothing than to
   hide the drive from eCS. No data gets lost! Only the drive letter
   assigned to that specified volume is freed for further use.
- go back to the next step using another drive on the OLD disk

Yes, you can do these steps parallel ion multiple volumes, so you will 
reduce the number of times you have to fire up LVM.
In standard eCS requires in maintenace and install boot:
drive letter R: for the CD drive  (changebale in preboot stage)
              Z: for a memory disk that holds the running system
                 you may change that in preboot stage too


After you've copied all and anything from the old drive to the new one 
you may decide to remove the old drive from the system - but when not,
you may simply go into LVM and hide all the drives on the NEW drive,
unhide (means assign the drive letters the partitins had had on the 
OLD drive, boot up to the old system.
Boot from CD, fire up LVM again, hide all the drives on the OLD drive, 
assignn drive letters (the original ones) to the volumes on the NEW 
drive and thereafter boot the new system from the NEW drive.

Whenever you need acces to a volume currently hidden you have to do 
nothing than
- fire up LVM
- assign a (free) drive letter to the volume you will handle now
- quit LVM with save - and use the newly assigned drive.

At least a question to you:
Why does you need so many different drives?

At least, you can hide all drives of all windows partitons you need no 
access to from eCS. Windows will use its own old cheme to give its 
drives the drive letters - so even if you hides C: D: E: F: G: - and 
all them are drives windows should acces windows will see them - but 
eCS will show you the drive letters as unused!

With a little bit more experience you can even use the drive windows 
sees as D: in eCS as X: or M: and have as C: and D: volumes only eCS 
can access. This changes nothing in the behavior windows has - but can 
give you more drive letters free.
