Use of Configuration file in other appliance

[Chandan Visweswara]

We have a disaster recovery ESA which needs to be in-sync with the production ESA. All the appliances are C670s. Is there an easier way to synchronize both production and DR appliance other than clustering? Can configuration file from production ESA be imported to the ESA in DR?

[Robert Sherwin]

As long as they are both running the same AsyncOS revision - yes.  

Save the production ESA configuration.

Save the DR ESA configuration.

Open both with text editor (Notepad++, etc.) and copy the "Network Configuration" section for the DR ESA.  Paste this same section to the production ESA configuration - and save as different file name, ie. new_DR_esa.xml.

Load this configuration from the DR ESA, submit/commit.
