A common tool that is used for X2P & X2V migrations is called PowerConvert from Platespin. Generally speaking the servers that are being migrated are put on the same internal network segment and therefore relatively easy to migrate. However, I wanted to examine how the process works if that is not the case and one or more of the elements are segregated by a firewall.
There are three elements involved in the migration process:
- Source Server
- Destination Server
- Platespin Powerconvert Server
The communication between these elements is over the following ports:
Server Discovery:
22 TCP SSH Port used when discovering Linux source servers or VMware
ESX/VMware Infrastructure 3 Servers443 TCP SSL Port used to connect to the VI3 web services when discovering ESX servers.
135/445 TCP For DCOM/RPC communication as PowerConvert utilizes WMI when discovering Windows based servers so that no manual configuration is required
**WMI (RPC/DCOM) may use TCP ports 135 and 445 as well as random/dynamically assigned ports above 1024.
Server Conversion:
80 TCP – For HTTP communication between the PowerConvert Server and the source/target machines.
443 TCP – For HTTPS communication (if using SSL) between the PowerConvert Server and the source/target machines. This is also the default port for the VMware Infrastructure 3 Web service.
3725 TCP – File Transfer port used between the source and target machine.
SMB (TCP 139, TCP 445, UDP 137,UDP 138) – File Transfer of the Take Control folder (i386) and files from the PowerConvert server to the source server.
135/445 TCP – For DCOM/RPC communication as PowerConvert utilizes WMI when taking control and rebooting the source server.
**WMI (RPC/DCOM) may use TCP ports 135 and 445 as well as random/dynamically assigned ports above 1024.
These ports must be opened on the firewall to allow the conversion to complete. An alternate method would be to temporarily place a PowerConvert Server in the DMZ.
