ZFS Zpool upgrade question

[bsd at todoo.biz]

Hi folks, 


We have moved our server from 9.2 to 9.3 and there seem to be a new version of ZFS available with a new feature set. 

We are backing up our data on FreeNAS which has the same ZFS version for the moment. 

> ZFS filesystem version: 5
> ZFS storage pool version: features support (5000)



• Can we leave with a non updated version of a ZPool on a server? What are the risks ? 

• Can my server zfs send | receive It’s data on different version of ZFS on send <> receive side ? 




Sincerely yours. 

G.B.
