And the following is the pros and cons of each migration method.

EMC SANCopy

Pros:

  • It can be migrated each source LUN to the target array one by one.
  • Any FC ports can be configured as SANCopy port on each Storage controller, and SANCopy port and host port can be running at the same time.
  • All migration operation can be executed on EMC Unisphere (VNX management server), optional migration server installation is not required.
  • SANCopy license is bundled on VNX storage.

Cons:

  • SANCopy is not supported incremental mode if the source array is 3rd party model.

HP 3PAR Online Import

Pros:

  • The destination HP 3PAR StoreServ Storage system must have a valid HP 3PAR Online Import or HP 3PAR Peer Motion license installed. By default it has 180 days Peer Motion temporary license installed.

Cons:

  • Each migration definition cannot be migrated each source LUN to the target array one by one, ie it will migrate all LUNs to target array if it has 3 three LUNs on EMC Storage Group when it starts migration session.
  • All migration definition can only be executed on 3PAR Online Import Unity which is the other management host for data migration.
