If you are running ESXi 5.5 with VSAN, DO NOT upgrade the ESXi host from 5.5 to 6.0. When mixing ESXi 5.5 and 6.0 in the VSAN cluster during the host upgrade, it can cause permanent data loss. See this VMware KB2139969 for more information. As December 25, 2015, no fix is available yet.
If you have to upgrade to ESXi 6.0 now, the safe approach is to migrate the VMs on the VSAN to other non-VSAN storage prior to the upgrade.
