What can be impact of Maintenace Silver license expiry

Hello All,

I am back with a doubt this time not an issue for a change :)

I am getting a notification in my ACC(Astaro Command Center - Yes we have upgraded our ASG soft appliance to Sophos UTM but not the ACC to UTM yet) that my MaintenanceSilver license subscription will expire in 15 Days.

So i would like to know here that if i dont renew my license then what impact i will be having in my existing ACC. I mean will any feature be disabled or just that i wont be getting any support from Astaro/Sophos. Also the regular Executive Reports and Configuration Autobackup will continue or they will be disabled. And most importantly we are planning to upgrade our ACC to Sophos UTM so will there be any hurdles in the process due to the expired license?

I would really appreciate if someone can explain me the detailed list of consequences of not renenwing the license after expiry if i have missed out of anything so i can try to convince my management to renew it asap.

Thanks,
Dhyanesh
