The customer is currently using the first node in production. The HA license is already applied to the first node.
The first node is installed with 7.0.1 SR1 with SQL server.
Now, I need to add the second node and I have some questions before I start building the server.
1) After installing the UCCX software, I will install the SQL server to the second node. Should I apply SR1 before I start the initial configuration? if not, when should I do it?
2) After I complete the initial configuration, what are the major steps I need to complete so the two servers can work together as HA? How do I make sure everything synchronize OK? How do I make sure CTI ports are created for the second node?
3) Is there any process that will interrupt the functions of the first node since it's in production right now? Should this integration be done after hours?
Note: I have done HA installation. but in all cases I have build two servers at the same time and configured them as HA before they go to production.
Thanks in advance
