Hi Giacomo
A device we sometimes use for these kinds of migrations is the Vicom (http://www.vicom.com/index.htm).%C2%A0 With a Vicom you can do online and offline migration. That said, you will nonetheless normally need at least one reboot because you have to uninstall the old multipathing software and install the new software.
I tend to be a bit conservative and prefer to do an off-line migration, for the simple fact that if something were to go wrong I could go back to the previous scenario. Admittedly one is not always afforded this luxury.
Generally after such a change I want to see the host pass a reboot-test anyway to know that if there were ever a power outage everything would come back on-line.
cheers Kenneth

Hi all,
once upon a time there was “ReplicatorX”…and now? ☺ Anyway I’ve never used it and I don’t know about its pros and cons.
I should plan a SAN data migration from dozens of servers and hundreds of LUNs on HP EVA 5000, IBM DS 4800, EMX CX700 and 300 and so on…
…and all of this has to be performed online, with no disruption, better if agentless (os are Windows, Linux, AIX and more, cluster based on Windows, RHEL, Suse, Oracle…)
Just one restart could be admitted for each systems…
Any suggestion, tools …
Thanks in advance,
