Cleanly Migrating to new Fiber Director Switches

[Arpotu]

Hello,

I have several SAN LUNs on a server, all added to LVM.  Coming soon, the
fiber between the HBA cards and the director switch will be moving to a
new switch.  The SAN admins say the SCSI ID's *might* change in the move. 
Question is - is there a "clean" way of migrating the LVM (intact) to the
new fiber switch?  The SAN admins say I will be getting the same LU's
back; I just have to ensure the LVM volumes get put back in the same
order.

Thanks,
Arpotu.
