• 2^nd Generation Drobo (FireWire 800) to Drobo S
• 1^st Generation Drobo (USB-only) to Drobo S

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. Please note that once you move drives from a Drobo to a Drobo S, you will no longer be able to use them in the Drobo.

2^nd Generation Drobo (FireWire 800)

Moving your data from a 2^nd 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.

1^st Generation Drobo (USB-only)

Moving your data from a 1^st 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 files from 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, 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 step 4.

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.

¹1st 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.
