Decide whether to use the aggregate relocation procedure
This content describes how to upgrade storage controllers in an AFF A700 HA pair with new AFF A900 controllers, while keeping all the existing data and disks. This is a complex procedure that should be used only by experienced administrators.
Use this procedure under the following circumstances:
You have verified with your NetApp sales representative that you have received an AFF A900 controller module and NVRAM module and the parts required for the upgrade.
You are running ONTAP 9.10.1 or later.
You do not want to add the new controllers as a new HA pair to the cluster and migrate the data by using volume moves.
You are experienced in administering ONTAP and are comfortable with the risks of working in diagnostic privilege mode.
Do NOT use this procedure under the following circumstances:
You are using FlexArray Virtualization Software on AFF A700 systems.
You are using a shared switch for cluster-interconnect and Ethernet attached storage.
For upgrading Fabric MetroCluster or MetroCluster IP configurations, see References to link to the MetroCluster Upgrade and Expansion content.
|You can use NetApp Storage Encryption (NSE) and NetApp Volume Encryption (NVE) with this procedure.|
If you prefer a different method of upgrading the controller hardware and are willing to do volume moves, refer to References to link to Upgrade by moving volumes or storage.
