Yes it is safe, it does not upgrade to the next release.  The only
difference from upgrade (I believe) is that any new packages required
will also be installed.  When you do an update through Update Manager
it effectively does dist-upgrade.

The command to upgrade to the next release of Ubuntu is do-release-upgrade.
