Yes you can do it through the GUI aka GroupManager... but - You cant upgrade directly to 9.x because your 5.2 is to old - With 8.x they remove the support for https. So dont be panic when you cant get access to GroupMGR... correct your browser bookmark from [URL] to [URL] Take care of default snapshot schedule when you have specify a snapshot reserve to a given volume- Dont forget the Drive FW update!!!! (not possible to apply through GroupMgr GUI!- Your SANHQ needs an update to (Server 2008r2 not supportet anymore!?!?!!) There is a "how to".... which contains a matrix for the FW upgrade path. There is a FW Upgrade Tool available which can help to prevent not to shoot your self into foot. It can be used for FW and Drive update as well. Note!: A FW upgrade means a Controller Module failover.... which means a short period of time with no access to the volumes for your servers. Be sure that you apply the best practice for your Host OS (Windows, ESXi ....)  We do FW upgrades when there is low IO on the systems.  Regards,Joerg
