5N to 5N2 Migration, will 64TB disk packs have penalty?

Current 5N owner, have high load and considering upgrade to a 5N2

Reading migration instructions, it’s noting disk packs with a max volume of 16TB will have I/O performance penalties

Does this mean the 64TB disk packs (that came with a 5N firmware upgrade) do not?

Yep. the 64TB volumes from the 5N will have full performance on the 5N2. Lucky you for already having the new file system. I am in the middle of the transfer over nightmare, in order to arrive on the new file system, and it is certainly not fun. lol
