Drobo Migration
Migrating Your Data Between Drobo Products

Drobo Migration

When it comes to upgrading your Drobo to a larger or newer version, you have several options. Use the links below to navigate to the scenario that best fits your current configuration. In most cases, migrating your "disk pack" (set of drives) from an older Drobo to a newer one is as simple as removing them from the older one, and placing them in the new one. Also note that in most cases migrating drives is a one-way operation. Once you move drives, you will no longer be able to access the data they contain with the older Drobo.

Migrating is as Easy as 1 – 2 – 3

Step 1

Upgrade firmware on both Drobos
Step 1 Upgrade firmware on both Drobos

Step 2

Power off Drobos and move Drives
Step 2 Power off Drobos and move Drives

Step 3

Power on and connect to your new Drobo
Step 3 Power on and connect to your new Drobo

NOTE: The following migration option is NOT supported: DroboPro to a Drobo other than DroboPro, that is, only DroboPro to DroboPro is supported.

UPDATE: Disk packs from Drobo (Gen 2) and Drobo S can be migrated to the new Drobo 5D. Since Drobo Mini introduces a new form factor  for drives, only migration from another Drobo Mini is supported.

Specific migration options are documented as follows:

WARNING: DO NOT migrate drives when either Drobo is turned on. This can result in data loss.

Migrating your data from Drobo to Drobo S:

IMPORTANT! Disk packs created or updated on Drobo Gen 2 running firmware version 1.4.0 to Drobo S firmware version 2.1.1 and earlier is not currently supported.

Please check to ensure you have the latest Drobo Dashboard and firmware on both Drobo and Drobo S before moving disk packs. Migrating drives to a Drobo S is a one-way operation, that is, once you move drives from a Drobo to a Drobo S, you will no longer be able to use them in the Drobo.

2nd Generation Drobo (FireWire 800)

2nd Generation Drobo (FireWire 800) to Drobo S

Moving your data from a 2nd Generation (FireWire 800) Drobo to a Drobo S is simple1:

  1. Put both your Drobo and Drobo S into standby using Drobo Dashboard or your operating system and then power off each array.
  2. Remove ALL disks from Drobo and insert ALL disks into Drobo S.
  3. Power Drobo S back on.

1st Generation Drobo (USB-only)

1st Generation Drobo (USB-only) to Drobo S

Moving your data from a 1st Generation (USB-only) Drobo to a Drobo S:

  1. Connect Drobo S to your computer and ensure it has sufficient free capacity to accommodate the additional data from Drobo.
  2. Copy ALL filesfrom Drobo to Drobo S.
  3. Verify ALL files are in place and fully accessibly on Drobo S
  4. If you would then like to add the drives from the Drobo to the Drobo S, remove the drives from Drobo and place them one at a time in the free data bays in Drobo S.

    Note that this will ERASE ALL DATA on these drives. This step cannot be undone. If you aren't sure that you've successfully copied all data onto Drobo S, do not complete this step.

NOTE: If your Drobo was formatted using Drobo firmware v1.03 or earlier, you will be unable to directly swap your drives from Drobo into Drobo S. This applies to most but not all 1st Generation (USB-only) Drobos. When you insert the disks into Drobo S a warning dialog will inform you of this, pointing you to this webpage. This process is necessary to upgrade you to the latest software that ensures maximum expandability in the future.

1 1st Generation (USB-only) Drobos formatted using Drobo firmware v1.10 or later may also follow these instructions. You can determine which upgrade path is necessary by inserting your whole Drobo disk pack in Drobo S. If you receive an error message, please follow the steps for a 1st Generation (USB-only) Drobo.

Migrating your data from a Drobo FS to Drobo 5N:

Migrating your data from a Drobo FS to Drobo 5N

Disk Pack Migration Best Practices

Option 1: Populate Drobo 5N with new drives and copy data from a Drobo FS over the network

Advantages:

  • Read/Write performance fastest – Read and write performance increased due to new drive and format optimisations.
  • Zero down time – Drobo FS shares are still available for use while copying data to the new Drobo 5N.
  • Redundancy – Existing data remains on the Drobo FS.

Disadvantage:

  • Cost – Additional drives to purchase for the Drobo 5N.
  • File Transfer Time – Depending on network connection and amount of data transferred, this can take hours.
  • Setup – Requires creating newusers, shares and mounting them on each host on the network.

Directions

  1. Insert new drives into the Drobo 5Nwith capacity greater than or equal to existing Drobo FS.
  2. Ensure that the latest version of Drobo Dashboard is installed on a host computer. (See here for latest version: http://www.drobo.com/support/updates.php )
  3. Ensure that both the Drobo FS and Drobo 5N are updated to the latest version of firmware by "checking for updates" in Drobo Dashboard.
  4. Connect the Drobo 5N to network and power it on.
  5. Copy ALL files from the Drobo FS to the Drobo 5N over the network.
  6. Verify ALL files are in place and fully accessible on the Drobo 5N.

Option 2: Migrate Drobo FS disk pack to Drobo 5N

Note: A disk packrefers to all drivesinstalled in a Drobo. Any drive inserted into an existing disk packwill be erased before being added to the disk pack.

Note: Disk pack migration involves moving ALL drivesin the disk packfrom one Drobo to another.

WARNING! Do not migrate drives when either Drobo device is powered on. Do not mix drives from different disk packs. This can result in data loss.

Advantages:

  • Cost – No need to purchase additional drives
  • Ease of setup – Maintains all shares, permissions, and passwords from the Drobo FS
  • Fastest transfer of data to the Drobo 5N – As fast as powering down the Drobo FS, migrating the disk pack to the Drobo 5N and powering it on.

Disadvantages:

  • Read/Write performance – Read and Write performance about 75% compared to a Drobo 5N with a new disk pack.
  • Down time – Requires powering off the Drobo FS in order to migrate the disk pack.

Directions

  1. Ensure that the latest version of Drobo Dashboard is installed on a host computer. (See here for latest version: http://www.drobo.com/support/updates.php )
  2. Ensure that both the Drobo FS and Drobo 5N are updated to the latest version of firmware by "checking for updates" in Drobo Dashboard.
  3. Safely power down both the Drobo FS and Drobo 5N.
  4. Remove ALL drivesfrom Drobo FS and insert ALL drivesinto the Drobo 5N.
  5. Power Drobo 5N back on. Within a few minutes,shares, data and userswill be visible on Drobo Dashboard. Do not reset or unplug your Drobo during this process.

Migrating your data from a Drobo or Drobo S to Drobo 5D:

Migrating your data from a Drobo or Drobo S to Drobo 5N

The Drobo 5D supports migrating entire disk packs from a Drobo or Drobo S, preserving all the data and volumes you created. You can also migrate disk packs from one Drobo 5D to another. To ensure a safe and successful migration, carefully follow the steps below.

Notes:

  • A disk pack functions as a unit. When you migrate a disk pack, you move ALL the drives from one Drobo device to another. Only after migration of the disk pack is complete can you add additional drives to the new Drobo device, one at a time, if desired.
  • If you are migrating the disk pack from a Drobo or Drobo S to a Drobo 5D, note that this is a one-way migration. After the migration, you will not be able to use the disk pack in the Drobo or Drobo S.
  • For information on migrating data (as opposed to the disk pack) from one Drobo device to another, see Drobo Migration at the top of this page.

Warning! Do not migrate drives when either Drobo device is powered on. This can result in data loss.

Directions:

  1. Ensure that the latest version of Drobo Dashboard is installed on a host computer. (See here for latest version: http://www.drobo.com/support/updates.php )
  2. Ensure that both the Drobo or Drobo S and the Drobo 5D are updated to the latest version of firmware by "checking for updates" in Drobo Dashboard. To do this:
    • Ensure you have set up your Drobo 5D (but without inserting drives) and connected it to your host computer.
    • Ensure that your Drobo or Drobo S (with its drives) is still connected to the host computer.
    • In Drobo Dashboard, on the All Drobos page, select the Drobo or Drobo S, and then click the Tools option on the Navigation menu.
    • In the Software Updates area of the Tools page, click the Check for Updates option
    • If needed, follow the same steps to ensure the Drobo 5D has the latest firmware.
  3. Safely shut down the Drobo or Drobo S and the Drobo 5D.
  4. Remove ALL drives from the Drobo or Drobo S and insert ALL drives into the Drobo 5D.
  5. Turn the Drobo 5D back on by pressing its power toggle button.
    The Drobo 5D may take a few minutes to boot up. When finished, all the data and volumes will be available on the Drobo 5D as it was on the Drobo or Drobo S.

Note: You can also follow these steps to migrate a disk pack from one Drobo 5D to another Drobo 5D.

Migrating Your Data from Drobo FS or 5N to Drobo 5N2:

Migrating your data from a Drobo or Drobo S to Drobo 5N

Disk Pack Migration Best Practices

Option 1: Populate Drobo 5N2 with new drives and copy data from a Drobo FS or Drobo 5N over the network

Advantages

  • Read/Write performance improvement – Read and write performance increased due to new drive and format optimizations.
  • Zero down time – Drobo FS / Drobo 5N shares are still available for use while copying data to the new Drobo 5N2.
  • Redundancy – Existing data remains on the Drobo FS / Drobo 5N.
  • Increased capacity - The maximum volume size on the Drobo FS is 16TB (ext3 filesystem), the same goes for the Drobo 5N disk packs (created before 3.5.0 firmware). The 5N2 has 64TB volume size (ext4 filesystem).

Disadvantages

  • Cost – Additional drives to purchase for the Drobo 5N2.
  • File Transfer Time – Depending on network connection and amount of data transferred, this can take hours.
  • Setup – Requires creating new users, shares and mounting them on each host on the network.

Directions:

  1. Insert new drives into the Drobo 5N2 with capacity greater than or equal to existing Drobo 5N or Drobo FS.
  2. Ensure that the latest version of Drobo Dashboard is installed on a host computer. (See here for latest version: http://www.drobo.com/docs)
  3. Ensure that both the Drobo FS / Drobo 5N and Drobo 5N2 are updated to the latest version of firmware by "checking for updates" in Drobo Dashboard.
  4. Connect the Drobo 5N2 to network and power it on.
  5. Copy ALL files from the Drobo FS / Drobo 5N to the Drobo 5N2 over the network.
  6. Verify ALL files are in place and fully accessible on the Drobo 5N2.

Option 2: Migrate Drobo FS or Drobo 5N disk pack to Drobo 5N2

Notes:

  • A disk pack refers to all drives installed in a Drobo.
  • Disk pack migration involves moving ALL drives in the disk pack from one Drobo to another.
  • We advise that the disk pack is in an all green state and data is accessible on their Drobo FS / Drobo 5N before migrating the pack to 5N2.

Warning! Do not migrate drives when either Drobo device is powered on. Do not mix drives from different disk packs. This can result in data loss.

Advantages

  • Cost – No need to purchase additional drives
  • Ease of setup – Maintains all shares, permissions, and passwords from the Drobo FS / Drobo 5N
  • Fastest transfer of data to the Drobo 5N2 – As fast as powering down the Drobo FS / Drobos 5N, migrating the disk pack to the Drobo 5N2 and powering it on

Disadvantages

  • Read/Write performance – Read and Write performance about 75% compared to a Drobo 5N2 with a new disk pack, if the Drobo FS / Drobo 5N have a 16TB volume
  • Total Volume - If the maximum volume size on the Drobo FS / Drobo 5N is 16TB. The maximum available usable capacity will stay at 16TB, if the pack is migrated to the 5N2.
  • Down time – Requires powering off the Drobo FS / Drobo 5N in order to migrate the disk pack.

Directions:

  1. Ensure that the latest version of Drobo Dashboard is installed on a host computer. (See here for latest version: http://www.drobo.com/docs )
  2. Ensure that both the Drobo FS / Drobo 5N and Drobo 5N2 are updated to the latest version of firmware by "checking for updates" in Drobo Dashboard.
  3. Safely power down both the Drobo FS / Drobo 5N and Drobo 5N2.
  4. Remove ALL drives from Drobo FS / Drobo 5N and insert ALL drives into the Drobo 5N2.
  5. Power Drobo 5N2 back on. Within a few minutes, shares, data and users will be visible on Drobo Dashboard. Do not reset or unplug your Drobo during this process

Migrating Your Data to Drobo 5D3:
