Redhat 4 host based migration

Hi,

I need to migrate using Redhat 4 as host based migration,EMC Clariion to VNX.

Please what are the best ways to perform online migration,with users working on the box?The file system is ext3 and the source logical voulumes are raid 1.

- adding the 3rd LUN(from VNX) to the current raid1 logical volume
- using rsync between 2 boxes with redhat 4,one box has raid 1 logical volume and the other one has new LUN(VNX).NFS exports the file system on the LUN in VNX and mount this on the other box.Then tar,cpio.
- pvmove,only if I do not need the data in old raid 1 logical volume.
- split raid1 into 2 submirrors and mirror one of those submirrors with LUN in VNX.

tnx a lot,
marius
