This is the final blog in a series on what’s new with clustered Data ONTAP 8.3. The last blog in the series highlighted data migration tools.


As discussed in this blog series, clustered Data ONTAP 8.3 has many new features including advanced drive partitioning, MetroCluster, and IPspaces, plus increased performance and other enhancements, and we expect this release to be compelling both for existing clustered Data ONTAP users, and for those who have been waiting for the right time to upgrade.


Two things to keep in mind when considering upgrading from 7-Mode:

  1. Data ONTAP 8.3 only supports cluster operation; it does not support 7-Mode.
  2. Data ONTAP 8.3 supports only 64-bit aggregates which provide larger aggregate and volume sizes and enable advanced features including compression, Flash Pool, and storage-efficient SnapVault. More than 100,000 installed NetApp systems are already using 64-bit aggregates.
    • In-place, nondisruptive expansion to 64-bit aggregates is supported in Data ONTAP 8.1.4 P4 and 8.2.1 and higher. It does not require any additional drives.
    • 32-bit aggregates must be converted before an upgrade to 8.3.
    • 32-bit Snapshot copies must be deleted or aged out prior to upgrading to 8.3.
    • SnapMirror and SnapVault relationships also require 64-bit aggregates.





To prepare for Data ONTAP 8.3, you should:

  • Upgrade to 8.2.1 or later and convert any remaining 32-bit aggregates to 64-bits as soon as possible.
  • Age out or delete any 32-bit Snapshot copies before upgrading to 8.3.
