What Are the Disk Requirements for Source and Target Servers?

Note that:

• SMS imposes a disk limit on source servers due to ECS constraints. While an ECS supports up to 24 disks, SMS reserves one slot for a temporary disk during migration. This means that a source server can have a maximum of 23 disks.
• If you do not need to adjust disk and partition settings for a source server when you migrate it, make sure that:
  • The target server has at least as many disks as the source server.
  • Each disk on the target server is at least as large as its corresponding disk on the source server.

• If you need to adjust disk and partition settings for a source server when you migrate it, make sure that:
  • The target server has at least the number of disks you specify during the adjustment.
  • Each disk on the target server has at least the space you specify during the adjustment.
