Have to ask this question separately in a new thread, because on other threads people jump into answering without reading the question first.
OK, here are the conditions:
ONTAP 7.3.4 with 32 bit aggregates volumes.
HEAVY use of file based flexcloning - on some volumes space savings exceed 70%. For example real data on a volume is 1TB and logical volume size is 8TB. We are already using >200% of usable capacity due to file based flexcloning.
Goal - migrate/upgrade the storage system to ONTAP 8.0.1/8.x.x with 64 bit aggregates/volumes WITH THE PRESERVATION of file based flexcloning savings.
Current methods - NDMP or QTS ARE NOT acceptable because they eliminate file based flexclone savings.
Question: WILL it be possible with upcoming releases of ONTAP? I know that NOW it is NOT possible.
Thanks in advance.

The rumours are, future Data ONTAP versions (I have heard about 8.1) will enable 32 => 64 bit conversion in place. I expect in this case all volumes will be retained "as is" together with all space savings.
