For example real data on a volume is 1TB and logical volume size is 8TB. We are already using &gt;200% of usable capacity due to file based flexcloning.</P><P></P><P>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.</P><P>Current methods - NDMP or QTS ARE NOT acceptable because they eliminate file based flexclone savings.</P><P></P><P></P><P>Question: WILL it be possible with upcoming releases of ONTAP? I know that NOW it is NOT possible.</P><P></P><P></P><P>Thanks in advance.</P></BODY></HTML> Thu, 05 Jun 2025 07:01:55 GMT https://community.netapp.com/t5/ONTAP-Discussions/upgrade-from-32-bit-to-64-bit-aggregate-volumes-with-flexclone-space-savings/m-p/58417#M13723 irakli_natsvlishvili 2025-06-05T07:01:55Z Re: upgrade from 32 bit to 64 bit aggregate/volumes with flexclone space savings intact https://community.netapp.com/t5/ONTAP-Discussions/upgrade-from-32-bit-to-64-bit-aggregate-volumes-with-flexclone-space-savings/m-p/58421#M13724 <HTML><HEAD></HEAD><BODY><P>The rumours are, future Data ONTAP versions (I have heard about 8.1) will enable 32 =&gt; 64 bit conversion in place.
