I recently had to re-deploy the ESRS gateway at a client.

Question I have is, how do I remove the original Gateway from  the ESRS service link.

I have moved all devices from the old to the new but the old Gate still shows up.

Old serial number is ESRSVE_4157803_15090706533898

New working one is ESRSVE_4157803_16053007263052

Also, I have to install a new version i.e. 3.10 as I am currently running 3.02

Can I use the existing serial number?
