Migrate data to new SAN storage

Hello all,

We are needing to move some data from one lun to another lun on our SAN.
Let's say the source is drive U: and the target is drive X:

After we copy the data to fron U: to X: we need to change the drive letter
on X back to U:. This sounds simple but I would think drive signatures would
prevent this? Or is just as simple as copy data to X: change the drive U: to
a different drive letter then change X: to U:?
