Initial installation of a failover-capable MOVEit Central node is the same as any MOVEit Central install or upgrade, since the failover capabilities are built into all copies of MOVEit Central 3.2 or later. However, to make a MOVEit Central system failover-capable, some additional steps need to be taken on each of the two nodes after the software have been installed on both nodes.
