Migrate to PowerVC appliance environment

Edit online

You can migrate from PowerVC 2.3.1, or later to PowerVC virtual appliance 2.3.3. The migration process preserves the existing configuration and data to ensure a seamless transition with minimal downtime.

Environment Scope

Table 1. Environment scope
Environment	Supported version	Deployment type
Source	PowerVC 2.3.1, or later	Single-node or Multi-node
Target (appliance)	PowerVC appliance 2.3.3	Single-node or Multi-node

Migration workflow

Perform the following steps to migrate PowerVC 2.3.1, or later to PowerVC virtual appliance 2.3.3:

Take a full PowerVC backup of the existing environment that includes both configuration and data by using the procedure at Backing up.
Notes:
- The backup must be created by using the following standard PowerVC backup command:
```
powervc-opsmgr backup
```
- PVCVA does not support compute plane node. Before you upgrade PowerVC classic to PowerVC appliance where compute plane node is registered for PowerVC classic, perform the following steps before you proceed with the upgrade:
  1. Move all the HMC hosts that are hosted in compute plane node to controller by using the hmc migratehost command.
  2. Deregister the compute plane node from PowerVC classic.
  3. Take a full PowerVC backup of the existing environment that includes both configuration and data by using the procedure at Backing up.
  4. Restore in PowerVC appliance by using the procedure at Migrate to PowerVC appliance environment.
Securely transfer the backup file from the PowerVC system to the appliance primary node of the PowerVC appliance environment by using the scp command to the path /powervchome/backups.
Run the following command to restore the backup on the PowerVC appliance controller:
```
powervc-opsmgr restore 
```
The restore process reconfigures services and restores all the data and settings from the backup file. You can review the logs in the /powervclog/opsmgr/artifacts  directory if there are any failures.

Once the restore operation completes successfully, PowerVC appliance automatically registers and manages all the compute, network, and storage resources that were present in the backup environment.

Notes:

Run the restore operations as the superadmin user.
Ensure network connectivity between PowerVC classic and PowerVC appliance systems if you use remote transfer.
The restore operation might take several minutes depending on the data size and environment configuration that causes a downtime.
It is recommended to perform the migration during a scheduled maintenance window.
