upgrade-oldest(8) selectively upgrades a Debian system by upgrading the packages with the oldest and most significant version numbers. It can be limited to certain sections, and the level of version differece necessary to trigger an upgrade can be controlled.
It is a simple Python script, but it is very powerful.

Suppose you have a slow internet connection and would like to upgrade your old Debian system. You have 3 opportunities:
apt-get upgradeto upgrade all your packages;
apt-get install packages1 package2 ... packageN;
upgrade-oldestto upgrade only packages, which version numbers changed most.
Debian Policy Manual, Chapter 3 - Binary packages describes Debian package management system and version numbering of binary packages. The version number of a package has the following format: [epoch:]upstream_version[-debian_revision].
.debfile has been made, if this is applicable. Usually this will be in the same format as that specified by the upstream author(s); however, it may need to be reformatted to fit into the package management system's format and comparison scheme.
upgrade-oldest compares version
number of currently installed package with version number of package
available for download splitting whole version number into parts, which
are compared to each other. Each part of version number has its level:
epoch is level 0, major upstream_version is level 1, next to major is
level 2 and so on. Package is upgraded when current version part is
lower than corresponding part of available version. You can set maximum
level to which such comparison applies with
option, by default it is 2.
