Subject: [lustre-discuss] Copying the data from one lustre to another lustre<br>
<br>
Hello Lustre Community,<br>
<br>
We have two lustre file systems. One with the version 2.12.6 and the one with 2.15.7.<br>
<br>
We want to copy the data from lustre with version 2.12.6 to the lustre with version 2.15.7. Which approach shall we use to copy/move the data.<br>
<br>
Need your support.<br>
<br>
regards,<br>
<br>
Ihsan<br>
