Upgrade stand alone to HA


Have a client that wants to get the HA system setup as they are growing and want to eliminate points of failure. Current system is a FreePBX Distro, kept up to date. Their operations are growing to support additional shifts and maintenance windows are becoming scarce. Is there an official “upgrade” process to enable the use of the HA module? Saw that the documentataion says to install using the HA mode, but this system wasn’t. I found this FreePBX HA Custom Installation and wondering if I can just install the additional yum packages - yum install drbd kmod-drbd pacemaker cman pcs ccs resource-agents resource-agent-freepbx rseries and then be ready to install.

Thanks in advance

Since HA is a commercial product, you should contact the Sales guys. I’m sure they have a wat forward for you.
