How to migrate Cacti to a new server
I had originally written this article for xmodulo . Cacti is a popular network graphing tool widely used by many service providers. For those of you who have been using Cacti to visualize the performance of various elements of your network, it is sometimes necessary to migrate Cacti and all its graph datasets from one server to another. Why? The current server may be old, or is running out of space and CPU, or you may simply want to move to new hardware platform. Whichever the case, it is possible to move Cacti data sets from one server to another, while minimizing disruptions in graph plotting. In this tutorial we will see just how easily we can do that. Step 1: Setting up Cacti in the New Server We will need to stop Cacti at the old server during the migration process. To minimize any gaps in graphs, we will prepare the newer server first (while Cacti at the old server is still running). We will start the process by installing Cacti in the new server.
