Restore from 20.0.3 to 21 GA on XGS118

Question

Hi, 
 I am trying to perform a restore to my new XGS118 from the latest backup on the XG115W. The XG115W is running v20.0.3 MR-3 and the options on the XGS118 are v20.0.2 MR-2 or V20 GA. 
 Do I need to download and instal v20.0.3 MR3 to the XGS118? 
 How do I perform a restore?

Backups always store the Firmware version. You cannot perform a "downgrade". 
 MR3 is a newer version than V21.0 GA. Therefore the only upgade is to V20.0 MR3.

You can take the new firewall to an older level of firmware, if needed, to meet the version you come from. Then upgrade the new system. 
 But pay attention here: the upgrade from 20.0.3 MR3 to 21.0.0.GA is not possible. 
 In this case I would recommend to go down to 20.0.2 MR2 with both systems, do a backup on the old system, restore it on the new system, then do the upgrade to 21.0.0 GA. Otherwise you are stuck.

Hello, 
 The backup restore compatibility available here: 
 https://docs.sophos.com/nsg/sophos-firewall/reference/backup_restore/port_mapping/en-us/index.html 
 Since your XG115W is running with v20 MR 3. The restoring device should also be running with the version v20 MR 3 or higher.
