Hi,
Good point about the IP address change. It can be done, but there are quite a number of steps involved (since SCI runs as a cluster with master and slave nodes, and if there is an IP change, every node needs to be informed, and the database updated accordingly, etc.)
However, the good news is we are going to make it easier for users to change the IP address. It will be available in the next release (SCI 5.1.2) which will be released very soon in the next couple of weeks. So stay tuned.
Thanks!
