Changing license to include a trial

Question

Hi, 
 We have a SG330 and have active subscriptions for Network Protection, Web Protection and Premium Support. I asked for a 'trial' license for the Webserver protection module and received a license key from Sophos. If I upload this to our device will it overwrite our existing subscriptions? Because looking at the license file, it does not mention our existing subscriptions and obviously I don't want to lose our already paid for subscriptions! 
 Thanks.

They had forgotten to include our existing subscriptions into the trial license.

Ok, I would ask Sophos or your reseller for a new trial license, which includes the existing subscriptions. A way to add a new license without unloading the installed one is not known to me.

Request a trial from your sophos partner for totalprotect trial 30day ;) 
 a new license file overwrites EVERY TIME the old license.
