Hi everyone.

I do not have much experience with VDX,

Below is my situation:

We have four VDX6740  in logical chasis mode.   Three  have no principal switch priority, we have configured Principal priority  1 on Master switch.  We will be moving to new data center, so my question is if we power down  these switches and then power them up at new data center, will they lose the config?

My second question is there any way  I can gracefully shutdown the switches rather than removing the power?

I have only been playing with these (a pair of VDX 6740T's in logical chassis mode) for the past few days but have learned that removing power without taking prior action will result in loosing their config. Last night I issued "chassis power-cycle-db-shutdown" on each node via console connection before I powered them down. This morning when I powered them back up they had not lost any configuration.

this is terrible. These switches cannot stand a power outage. They comes up with default config and this is very disruptive having services connected to them.
