Hello Sandeep,  This is a multi-layered. The short is yes. There was and should be a 7.2.1.1 (currently the recommended release as of writing) simulator. I searched and couldn't find it. However, I found a related article that has a link that did work, I will talk with IT about resolving this but for the time being please try: [URL]  As for upgrading your current Virtual it is absolutely possible, I am not currently aware of any negative side affects from doing this but you would just place the regular 7.2.1.1 file on your VM and do the upgrade just like it was a production cluster.  I stood up a single node using the referenced OneFS versions, dropped the install file through the default /ifs share on my VM and it upgraded very smoothly. It will yell at you a little on upgrade checks due to it still being a VM but see the output of work below along with 7.2.1.1 installation file link.  7.2.1.1 install file location [URL]  Isilon OneFS v7.2.0.1 MR-Cluster-1# cd /ifs/data MR-Cluster-1# ls OneFS_v7.2.1.1_Install.tar.gz MR-Cluster-1# pwd /ifs/data MR-Cluster-1# isi update Preupgrade check results: ==================== Cluster event checks ==================== Warnings: * Cluster contains unresolved critical events.
