[Lustre-discuss] Upgrading From Lustre 1.4 to 1.8

[Adam]

Hello,

Would lustre 1.8 be able to work with an LFS created by 1.4? The 1.8 
rolling upgrade strategy discussed on the Lustre wiki is wonderful ( 
http://wiki.lustre.org/index.php/Upgrading_to_a_New_Version_of_Lustre#Performing_a_Rolling_Upgrade), 
but it only mentions compatibility with 1.6; I'm curious if it 
would/should also work with an older version of Lustre like 1.4.

Thank you,
Adam
