A server administrator has been asked to move data between two different vendor storage arrays.
The LUN from the target array has been provisioned and is slightly bigger than the LUN from the
source array. The application must remain online during the entire migration process, including
removing the source array LUNs. Which of the following methods would be MOST appropriate?
A.
Use array based replication to make a block based copy of the data.
B.
Use an operating system based file copy tool to move the data to a new file system.
C.
Restore a copy of the data on to the target LUN from a recent backup.
D.
Use an LVM to create a host mirror between the source and target LUNs.
