Thank you @Peasant for the reply. I wanted to provide an update...

The process was actually much easier than expected. We just needed to:

1. Snapshot the original LUN.
2. Create the same mount point on the new server.
3. Copy the /etc/fstab entry from original server and write it to the /etc/fstab on the new server.
4. Present the snapshot LUN to the new server.
5. Reboot the new server.

This allowed us to to see the original data as expected.

Thanks again for the help..

NAME

       pvchange - change attributes of a physical volume

SYNOPSIS

       pvchange  [--addtag  Tag]  [-A|--autobackup y|n] [-d|--debug] [-f|--force] [--deltag Tag] [--metadataignore y|n] [-h|-?|--help] [-t|--test]
       [-v|--verbose] [-a|--all] [-x|--allocatable y|n] [-u|--uuid] [PhysicalVolumePath...]

DESCRIPTION

       pvchange allows you to change the allocation permissions of one or more physical volumes.

OPTIONS

       See lvm for common options.

       -a, --all
	      If PhysicalVolumePath is not specified on the command line all physical volumes are searched for and used.

       --metadataignore  y|n
	      Ignore or un-ignore metadata areas on this physical volume.  If metadata areas on a physical volume are ignored, LVM  will  not  not
	      store metadata in the metadata areas present on this Physical Volume.

       -u, --uuid
	      Generate new random UUID for specified physical volumes.

       -x, --allocatable y|n
	      Enable or disable allocation of physical extents on this physical volume.

Example
       "pvchange -x n /dev/sdk1" disallows the allocation of physical extents on this physical volume (possibly because of disk errors, or because
       it will be removed after freeing it.
