Thank you for the quick response.
How would I go about upgrading from GVM 9 to 10?
To avoid mixing different questions (about schedules and on how to do an update itself) i have split your question about updating into a separate thread.
The easiest way for you to update should be to contact the maintainer of your used linux distribution / packages and ask for an update.
Using the source based installation could be another possibility. For such setups some basic documentation on an update are available here:
