[Lustre-discuss] Migrate lustre 1.8 to 2.1 recommended procedure.

[Colin Leavett-Brown]

What is the recommended procedure to migrate a Lustre 1.8.3 filesystem 
to Lustre 2.1? Can I install a new Linux kernel, Lustre 2.1 rpms and 
attach the OSTs? Or do  I need to create a new filesystems and copy the 
data across?
