Yes.  Migrating from concatenated to striped LUNs is a normal practice.  There aren't any issues with this.  If I ever run into an emergency situation where I need to extend a LUN fast:  I concatenate additional space onto the existing LUN, then migrate to a striped LUN.  You can pretty much migrate a LUN (reserved LUNs,component LUNs not included) to any other unused LUN.  The underlying structure of the LUN doesn't really matter to Navisphere.  It will let you migrate all over the place, as long as the new LUN is the same size, or bigger.  The only real exception to this is a LUN used by a Celerra - Navi will let you migrate the LUN, but the Celerra won't like it.
Hello,  I have a meta lun with 2 components.  Comp 0 -> had 4 luns with 267 GB raid 1/0 Comp 1--_ had 2 lun with 402Gb raid 1/0  We want to get rid of the above lun and create a brand new lun with single component Comp0 and stripe the meta lun with 6 disk 1872GB and migrate the lun. Is it really possible to do this.
