Hi,

It depends on the load on system first of all while doing it online. What is the current layout and what will be used for mirroring, If it is LVM structure and you are planning to use mirror-Ux then It should be over 2-3 hours online and a bit less offline.

What is the fibre type /speed ? It will be faster is the layout is VxVm with licensed version as it supports multipathing with load balancing.

How many adapters?

To be frank can not say exactly with the information you provided.

HTH,
Devender
