The names of the port groups that are being migrated may exist on the target array, provided that the groups on the target array
have the initiators logged in into at least one port in the port group, or are visible in the LHT (Login History Table).
GENERAL CONSIDERATIONS AND LIMITATIONS
Migrating hosts must have access and be zoned to both the source and target array
Migrating hosts must use fibre channel connectivity
SESSION LIMITS
16 Storage Groups can be migrated concurrently.
o Child SGs do not count towards this limit.
Each Storage Group can contain up to 4096 devices.
HARDWARE AND SOFTWARE REQUIREMENTS
For full connectivity information see the following:
o RDF Interfamily Connectivity Guide
o NDM Connectivity Support Article (support.emc.com)
Solutions Enabler 8.3 or later
Unisphere for VMAX 8.3 or later
Solutions Enabler or Unisphere control host
Supported host operating system and multi-pathing software
Supported cluster software (if applicable)
To enable the ability for SGs with existing DR in SRDF/S mode to be migrated the following minimum code levels are required:
Vmax with Enginuity 5876.309.xxx & Fix 90270 (Epack)
VMAX3 or All Flash with HYPERMAX 0S 5977 Q2 2017 Release
Unisphere 8.4
Solutions Enabler 8.4 or later
CONFIGURATION REQUIREMENTS AND PREREQUISITES
Most of the steps for configuring and un-configuring NDM is done automatically using the environment setup and remove commands.
Prior to running the setup, the following is required:
• SRDF must be enabled in the bin file.
• The source and target arrays must have SRDF directors and ports configured.
• SRDF Ports on the Target array must be configured across at least two Directors with a minimum of 2 Ports up to a maximum
of 8.
• The SRDF ports between the source and target arrays in a Fibre Channel environment must be zoned to each other.
• A Solutions Enabler or Unisphere management host that sees at least one of the arrays must be available.
• Both the source and target array are connected to the same SAN.
For more information on the process to enable SRDF on the array for use with NDM, please visit KB article#495041 (web link below).

Prior to running the Create, the following is required:
• The host with the application being migrated must be zoned to the VMAX3 or VMAX All Flash.
