Which statement is true about converting an aggregate from 32-bit to 64-bit?
The correct answer is A. It is supported when adding disks. A NetApp 32-bit aggregate can be converted in-place to 64-bit format by adding disks to the aggregate, which triggers the expansion automatically.
Question
Which statement is true about converting an aggregate from 32-bit to 64-bit?
Options
- AIt is supported when adding disks.
- BIt is supported without adding disks.
- CIt is supported in maintenance mode.
- DIt now supported. You must use VSM to migrate 32-bit to 64-bit.

Why each option
A NetApp 32-bit aggregate can be converted in-place to 64-bit format by adding disks to the aggregate, which triggers the expansion automatically.
When new disks are added to a 32-bit aggregate, ONTAP automatically initiates an in-place conversion to the 64-bit format to accommodate the expanded capacity. This is an online operation - the aggregate continues serving data during the conversion - and adding disks is the only supported trigger for this conversion.
Converting a 32-bit aggregate to 64-bit without adding disks is not supported - the disk addition is the required mechanism that triggers the format expansion process.
The conversion is not a maintenance mode procedure - it is an automated online operation that occurs during normal cluster operation when disks are added.
Native in-place conversion triggered by disk addition is supported directly in ONTAP - migrating with VSM is not required, and the claim that conversion is unsupported is factually incorrect.
