migrate from ssa to san

Hi,

Do you have procedures to migrate ssa disks to san disk?

I don't have testing environment and I want my file system be migrated one at a time. I want it to be fast, I have only 15-20 hours to do it on every sunday 1PM till monday 7am. My largest file system is about 150G.

The AIX is 4.3.3 maintenance level 9.

Thanks in advance,
itik
