Configure a backup for virtual server configration along with setup

After the command

tmsh load sys config merge from-terminal

You will get a VI like screen where you can past the configuration (remove the create-time line)

The VI screen will tell you to press Ctrl D when finished or Ctrl C to quit.

I would recommend to test this first with the command:

tmsh load sys config merge from-terminal verify

When everything is ok and the new configuration is loaded you can save the configuration with

tmsh save sys config
