For data migration you can use the Data Protector. Take the backup of your data and restore it on the storage.
The other way of migrating your data is through SAN.If you use the Business Copy then you can use the BC SVOL's for this purpose.

If both arrays are connected to the host you can create a mirror copy of data (MirrorDisk/UX software is required) to the second array and remove the first copy.

Data Migration from a older storage Array to the new XP Storage works they have bought...

Data from one arrays is mirrored over the second. If you remove the mirror from first array the data will remain over the second.

For example:

lvextend -m 1 /dev/vgXX/lvol1 pvg_2nd_array

lvreduce -m 0 /dev/vgXX/lvol1
