Migrating FOG Server

Moving to a new FOG 1.6 server — including from an older 1.5.x server, which is a normal upgrade path — is covered by the 1.6 page. Moving a 1.5.x server to another 1.5.x server, with no version change, differs: there is no updatefog.sh or --channel, the certificate CLI is narrower, and --secureboot-ca-cert does not exist.

Which version am I on?

Check FOG Configuration → FOG Settings → General → FOG_VERSION in the web UI, or the version string printed at the top of installfog.sh.
