I have enquired with vendor.

what about existing licenses that are still v17.5? and lic 1C2? upgrade to v18.0 how?

All licenses were migrated to 1C4. 

is there a way to confirm that on the installed instance?

with all due respect is there an official document that describes the details? 

The migration was in April 2019. I am not sure, if there is any kind of information left on the platform. 

that was before I switched to Sophos! Purchased last one jan 2021 nothing was said. 

Please share a screenshot of your Licensing Page and Burr your Serialnumber and personal information. There should be a Hardware modell. 

YES I see it SFV1C4 SO THAT CONFIRMS IT!  I can safely add 2GB and upgrade it, correct?

Yes you can.
