.. See the upgrade considerations in this guide for *each applicable release*. 
   For example, if you are upgrading from 2.4.15 to 2.4.17, see *both* sections
   :ref:`section-index2416` and :ref:`section-index2417`. Together, these
   sections provide important upgrade considerations that apply when upgrading
   from your current to your new release.

Whether you will keep some of your legacy |me| systems or migrate
entirely to a new |me| release, read this guide to see what settings 
or other changes you may need to make before you upgrade all or part of your 
system. The full set of changes for your release is described in the *Release
Notes* section for your release:

* `What's New in 2.4.16 <https://community.rti.com/static/documentation/connext-cert/2.4.16/doc/html/release/whats_new_2416.html>`__
* `What's New in 2.4.15 <https://community.rti.com/static/documentation/connext-cert/2.4.15/doc/html/release/whats_new_2415.html>`__

This guide describes only those changes that may break old behavior.
