You can clone a host between one and 99 times. Clone a host to set up properties for similar hosts more easily. When a host is cloned, all the servers in the host are cloned as well with unique names. This feature allows a user to set up properties for similar hosts and servers easily in a matter of minutes.
You can clone a host as soon as you create it (that is fill a new Properties dialog and click OK). When you clone a host, a number of copies appear in the Enterprise data movement model (EDMM).
Cloning a host only creates a copy of the information about it in the EDMM. It does not ensure that your additional systems have the DBMSs or that tables with the same names as the ones on the original server exist on the clones. You must ensure that these are true before you commit a model with cloned servers.
Each clone is given the original host/server’s name and a number in ascending order. The name of the host/server to be cloned can be a maximum of 29 characters since the cloning process creates a name for each clone by adding 3 characters to the name.
You cannot successfully clone a host with multiple servers sending to each other.
