[HPDD-discuss] Upgrading lustre servers from 2.6.0 to 2.6.90 risks

Hello, Can someone here confirm if i'm safe from any risk of data corruption or any further troubles by upgrading my MDS and OSS servers software from the online feature release 2.6.0-RC2--PRISTINE-2.6.32-431.20.3.el6_lustre.x86_64 to the last 2.6.91 version ? or is there some modifications that may lead to a possible crash ? (proceeding to the usual stop-start services respecting the good order) We are running test over our new platform here that lasts for more consequent purposes and as the 2.7 will be out there shortly we want to keep it functionnal in 2.6.
