Changing license on UTM firewall

Question

Hello all,

Our licenses currently expired on our firewall (SG 3xx) nodes, and we will buy a renewal for them.

Problem is we need to completely change the license currently used on one of our nodes by one of another node which is not used anymore.
When change a license file to a new one, does the current configuration of the firewall get reset or will all the services (only accessible through network protection subscription) or we can change the license on the fly without fearing losing all current settings & configuration?

Best,

Alexis

Hello Alexis, 
 Good day and thanks for reaching out to Sophos Community. 
 Would there be any change on the license model / subscription feature that you will be renewing? https://docs.sophos.com/nsg/sophos-utm/utm/9.706/help/en-us/Content/utm/utmAdminGuide/MgmtLicensingUTM.htm If yes, and let's say you're cancelling out Emal and WAF License on the renewal. Current policy and protection for WAF and Email would not work as expected but you don't lose ALL current settings and configuration when you upload a new license on UTM. 
 You will just need to upload the .txt file from your MyUTM account - in which I assume you will renew with your Sophos Partner/AM -> upload it on your UTM under Management -> Licensing -> Installation -> Apply then you can verify the status of your subscription under Licensing -> Overview 
 Cheers,
