Upgrading to a 64-bit aggregate
For storage systems running Data ONTAP 8.1 and later, you can upgrade 32-bit aggregates to 64-bit aggregates by increasing their size beyond 16 TB. System Manager enables you to add disks to a 32-bit aggregate and upgrade it when the aggregate size crosses 16 TB.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
Ensure that the left navigation pane displays either the cluster hierarchy or the storage controllers hierarchy.
3.
In the navigation pane, click Storage > Aggregates.
4.
Select the 32-bit aggregate whose size you want to increase and click Add Disks.
5.
Select one or more disks and click Add.
6.
Select the confirmation check box and click Add.
This opens the Upgrade to 64 bit aggregate Wizard for upgrading the 32-bit aggregate.
7.
Type or select information as requested by the wizard.
8.
Confirm the details and click Finish to complete the wizard.
