Two computers running Windows Server 2008 or Windows Server 2012 and using the same type of database server(for supported operating systems and databases, see Requirements). Note: If you need to migrate MOVEit Central to a new server, these Knowledge Base articles can help:
MOVEit Central. The failover capability is built into all versions of MOVEit Central; however, it must be enabled by a special license.
A license that enables the failover capability. The same license key can be used on both computers.
A TCP connection between the two computers that allows access to ports 3472 and 3473. Also, if you use the MySQL database, NetBIOS over TCP must be enabled between the two machines to allow the very useful "Copy Database From" action to occur.
