Replacing NetScaler Appliance

Recommended Posts

Hi,

 

I am replacing a HA Pair of NetScaler MDX 5500 (running v9.3) to NetScaler MDX 5550. 

 

My plan was to do the following:

Copy config from 5500

Set up initial configuration on one of the new NetScalers 5550

Run in Batch Configuration of the config from legacy

Copy SSL certs and licenses over with WinSCP to new appliance

Test everything

Set up new HA pair with the other new appliance

 

Does this sound right? I understand I could go down the HA route, but I want to see what the best approach is?

You want to have the two steps in the reverse order as below otherwise the batch configuration will error if it can't find the SSL certs and keys when running the 'add ssl cerkey' commands:

 

Copy SSL certs and licenses over with WinSCP to new appliance

Run in Batch Configuration of the config from legacy

 

Also you will need to change the NSIP in the ns.conf file to the one configured on the 5550 before running the batch configuration.

 

Regarding what the best approach is will be subjective as the HA route should work just as well to achieve the same end.

An easier method is to do this:

  1. Make sure the new appliance is licensed and running your desired firmware level.
  2. Copy the cert files to the new appliance in /nsconfig/ssl.
  3. On the new appliance, go to /nsconfig and rename the ns.conf file.
  4. Copy the ns.conf file from the old appliance to the new appliance.
  5. Shut down the old appliance.
  6. Reboot the new appliance without saving the config. This is key. Don't save the config since it's already saved in the copied ns.conf file.
  7. When the appliance boots, it reads the config file and takes over the IP addresses.
