Hi Lavanya,
Im understanding you have two gateways (2200 and 4200) and a separate Security Management.
You are trying to replace 2200 with 4200? If this is the case you can follow this steps:
- Save a copy of clish configuration on 2200 Appliance with "save configuration" command on cli (copy from "show configuration" also works)
- Since 2200 Appliance has 6 physical interfaces and 4200 has 4 (without extra module), you will have to adapt the configuration in case the 2200 is using more than 4 interfaces (use VLANs instead for 4200)
- Perform a clean Install as Gateway Only for 4200 Appliance and save SIC password
- Once the configuration has been adapted (if it was neccesary), you can paste directly on 4200 Appliance CLI or manually configure each parameter through Gaia Portal
- On 2200 object in Security Management perform a SIC Reset. You can follow the security management steps on sk65764: How to reset SIC
- Change the appliance from 2200 to 4200 on drop down list of the object
- Verify your topology settings are correct
- Install policy
Take into account when you reset SIC, some certificate based technologies must be reestablished. Also as recommendation, install the latest GA JHF for R80.10
Also you can create a new object for 4200 Appliance and establish SIC. This new object must have a different name than 2200 Appliance. Since you have Security Management Server R80.XX, once created you can make right click on 2200 object --> Where Used --> Select Replace option.
This also would work, but I think you have to replace manually the object in some sections of the policy that cant be replaced this way.
Regards.
