I have a NodeJS instance on Amazon LightSail. I want to upgrade the underlying Operating System to a newer major version, say Ubuntu 18 LTS to Ubuntu 20 LTS.
When I create a new instance from the snapshot, I do not get the option of choosing the version of the OS, so the new instance will have the same OS ad the original instance.
Is it possible, from a snapshot running a previous OS version, to create an instance with a newer OS version? If not, is there an easy way to upgrade the OS of an instance, short of creating a new instance, installing programs and transferring data?
