Updating SUSE 12 SP5 from .173 - .191 (OFFLINE)

Hello to everybody on this forum. I currently have an August 2023 (4.12.14-122.173.1) of SUSE 12 SP5 installed on my VM. May I know the best way to update it to Febuary 2024 (4.12.14-122.194.1) via offline methods? I cannot connect my VM to the internet, but I can use another server that is internet facing to download files.
