3150, Ontap 8.0.1, MPHA in place, 32 bit root aggregate/volume.
Plan to upgrade to 8.0.2 and move root aggregate/volume to 64bit. What is safest and least intrusive way to do it? Will it require shut down of the storage system?
A reboot after copying the data to the new root volume is required to activate the new root volume: https://kb.netapp.com/support/index?page=content&id=1010097
