Hi, Like you had mentioned, The Mobility has to be done first with same size Vmax lun. Extra space can not be claimed in the traget lun. After the mobility job is complete, the 7 tb Vmax lun has to be extended.  Hope this helps.  Thanks, Sathya
Hi All  We need to migrate a lun from XIO - 7 TB to VMAX lun which needs to be 15 TB. Both are behind VPLEX. For this scenario, do we need to first use VPLEX Mobility and migrate a 7 TB XIO lun to 7 TB VMAX lun and then need to expand VMAX lun to achieve 15 TB    (OR)  can we use VPLEX Mobility and directly migrate from 7 TB XIO lun to a 15 TB VMAX lun.  Will the extra space on vmax lun be usable to store host IO  Your replies are appreciated.
VPLEX device mobility to a bigger sized lun
