This Knowledge Base article will guide you through the steps in order to migrate a disk-pack from one Drobo to another. While migrations between Drobo's of the same family are supported, it is important that these guidelines are followed. Read our web page entitled Drobo Migration to see which Drobo disk packs can be migrated to other Drobo products.
Important! In order to safely migrate a Drobo disk-pack onto another Drobo, the following criteria must be met:
When is it okay to Migrate:
Before Migrating, consider the following:
1. The newer Drobo models have a larger maximum volume size, 64TB/128TB.
2. The older Drobo models have a maximum 16TB or smaller maximum volume size. When you migrate or move the drives from an older model Drobo to a newer model Drobo, the smaller volume size will carry over to the new unit. This is okay but you will eventually hit a plateau where the smaller maximum volume size will be exceeded and the space beyond 16TB cannot be used to store data.
3. To resolve the 16TB maximum volume size limitation, you will need to backup all of the data on Drobo then perform the Erase and Factory Reset. Then copy the data back to Drobo: Drobo 5N; Drobo 5D: 64TB Volume Support. This can be done after you migrate is migrating is the only way to gain access to the data.
