Migrating data between appliances Performing appliance data migration
Prerequisites for the target appliance
Performing appliance data migration
1. On the target appliance, start data migration using the following CLI commands. After executing these commands,
you will be prompted to enter the encryption key passphrase used to setup the encryption key on the source
appliance. This passphrase will be used to import the encryption key on the target appliance. If no passphrase was
created, press Enter to continue.
<target appliance> > enable
<target appliance> # configure terminal
<target appliance (config)> # datamigration receive
2. On the source appliance, check whether cloud deduplication is enabled:
<source appliance> > enable
<source appliance> # configure terminal
<source appliance (config)> # no replication cloud-dedupe
If cloud deduplication is enabled, AltaVault displays a message asking if you want to disable cloud deduplication:
If prompted, enter
N (no).
The cloud deduplication status is needed in Step 3 for determining whether to use the metadata-only option.
Requirement Description
RAID groups The total number of target RAID groups must be equal to or greater than the number of source storage
shelves, including the source controller. For example, a SteelStore 3030 with 3 shelves would require an
AltaVault appliance with at least 2 shelves, which in turn supports 4 RAID groups. To gather shelf
information using the CLI, open a SSH session to the source appliance and issue the following command:
enable
configure terminal
show shelves
Time zone The time zone on the source appliance must match that of the target appliance.
Software version When the source is a SteelStore appliance, the target must be running AltaVault 4.1.1.
When the source is an AltaVault appliance, both source and target must be running the same software
version.
Appliance service Shut down the storage optimization service. To stop the service using the CLI, open an SSH session to the
source appliance and issue the following commands:
enable
configure terminal
no service enable
Network
connectivity
The target appliance must be minimally configured with a management IP address and IP addresses for
any data interfaces that the appliance will use to receive data during the data migration process. For
details on configuring the management and data interfaces, see “Modifying management interfaces” on
page 53 and “Modifying data interfaces” on page 54.
Data integrity The target datastore must be empty. Use the following CLI commands to format the local datastore:
enable
config terminal
no service enable
datastore format local
