If I was an AIX admin (or had an AIX admin I really trusted) I would use LVM within AIX for a smooth and fully online migration.
If that wasn't an option I would look at Online Import and if your VNX ticks all the boxes for support, I would definitely go down that route rather than Clonezilla. If your AIX ticks all the boxes I would even do it online... I'm guessing this would fall under MDM (Minimally Disruptive Migration) that requires the host to be shutdown and unzoned from the VNX during the start of the migration.
I've used Online Import multiple times for EVAs and for the most part it is basically the same as Peer Motion/federation which I've used even more times. Never had any issues with data consistency.
