Resetting the Windows user password can cause the loss of all locally collected data.\n\n### Requirements for VMware VMs\n\nTo use the `mcdc` CLI to collect data using VMware\ninventory discovery:\n\n- The machine running the `mcdc` CLI must be able to connect to your vCenter and ESX hosts. This includes opening all necessary ports in firewall rules and ensuring network connectivity between the `mcdc` CLI host machine and target vCenter server and ESX hosts.\n- The vSphere vCenter server must be version 5.5 or later.\n- The vSphere vCenter server must support TLS version 1.2 or later.\n- The username you pass to the `mcdc` CLI must have read privileges on one or more VMs. The `mcdc` CLI is only able to discover information about VMs that are accessible to the specified user. The read privilege is typically assigned to all roles except for `No Access`.\n- The username you pass to the `mcdc` CLI must have read privileges on the host ESX. If there are multiple ESX servers, then read privileges are required for every ESX that hosts a discovered VM.\n- The user running `mcdc` CLI must have read, write, execute privileges on the machine running the `mcdc` CLI.\n\nTo use the `mcdc` CLI to run the guest collection\nscripts remotely for VMware VMs:\n\n- You need the same permissions to run VMware discovery described earlier.\n- The username you pass to the `mcdc` CLI to connect to vSphere must have the following privileges on the VM: Guest operation modifications, Guest operation program execution, and Guest operation queries.\n- The VM user credentials used by the `mcdc` CLI to execute the script must have administrator privileges on the target guest machine for Windows VM.\n- Port 443 must be open from the `mcdc` CLI Linux station to all ESXI hosts.\n\n### Requirements for SSH collection\n\nTo use the `mcdc` CLI to run the guest collection scripts\nremotely using SSH:\n\n- The machine hosting the `mcdc` CLI must have\n SSH access to the target Linux machines.\n\n | **Note:** `mcdc` CLI doesn't support running the guest collection scripts remotely using SSH on Windows machines.\n\n### Requirements for IP range scan\n\nTo use the `mcdc` CLI to run an IP range scan:\n\n- Configure your network firewalls to enable ICMP requests on the network or machines in your infrastructure.\n- Give permissions to unprivileged users to perform a ping from the host machine. Alternatively, before running an IP range scan, run `sudo setcap cap_net_raw-ep ./mcdc`.\n\nRequirements for downloading and running guest collection scripts\n-----------------------------------------------------------------\n\n- `mcdc-linux-collect.sh` runs on all Linux versions.\n- `mcdc-windows-collect.ps1` requires PowerShell 2.0 or later (not PowerShell Core), and either a GUI shell (not server core) or .Net framework 4.5 or later. All Windows versions greater than or equal to Windows 8 and Windows Server 2012 support these requirements, as do the vast majority of Windows 7 and Windows Server 2008 R2 machines.\n\nWhat's next\n-----------\n\n- Learn how to [download the `mcdc` CLI](/migration-center/docs/download-collector-cli)."]]
