# Move SRDF pairs

Symmetrix Remote Data Facility (SRDF) facilitates the data replication from one storage system to another through a storage area network or Internet Protocol (IP) network.

## Prerequisites

See Roles and associated permissions to determine the user roles that can perform this task.

This operation is blocked on SRDF groups that Global Mirror uses.

## About this task

This procedure explains how to move the SRDF pair from one SRDF group to another. The move type can be a full move or a half move. A half move specifies to move only the local half of the SRDF pair. A half move on an SRDF 1 type pair results in only the R1 volume is moved. A half move on an SRDF 2 type pair results in only the R2 volume is moved. This procedure supports moving SRDF pairs to a SRDF/Metro group.

This operation can be invoked from multiple locations in the Unisphere user interface (Device group > SRDF Group, Device Group > SRDF Pairs, SG All Details > SRDF tab, PROTECTION dashboard) . Depending on where the operation is invoked, some of the steps below may not apply.
