Veritas LUN migrate query

Hi, We are migrating existing LUNS in veritas to new SAN.
But the LUNS presented at new SAN are of very less size. What would be the ideal way to migrate/move the data ?

Using VxVm 5.1 & VCS. Downtime of filesystem/application is fine.

Thanks in advance.

This is what am not getting quite well. Is that the space is more in the existing SAN than the new one you are going to use? I hope, that's not the situation.

Anyways, what method of migration are you going to follow? There are Array based migration methods/Veritas Based/Multipathing software based and so on. What storage models are involved in this? Is the source and target Arrays from different vendors? What's the host operating system? How many nodes are there in your setup? Which multipathing software you are using?

Please explain more about you requirement so I can give it a try!
