Re: [HPDD-discuss] Is rolling upgrade 2.4.2-->2.5.1 viable?

Hi, Rolling upgrade from Lustre 2.4.2 to 2.5.1 is supported and tested, allowing individual servers (or their failover partners) and clients to be upgraded one at a time without stopping the Lustre file system. The upgrade path is OSSs->MGS/MDS->Clients. -- Best regards, Yu, Jian From: HPDD-discuss [mailto:hpdd-discuss-bounces@lists.01.org] On Behalf Of E.S.
