+
+ The installation process will not over-write your existing
+configuration files. It will, however, warn you about the files it
+did not install.
+
+ For users upgrading from 1.x to 2.0, we STRONGLY recommend that 2.0
+be installed in a different location than the existing 1.x
+installation. Any local policies can then be migrated gradually to
+the new 2.0 configuration. While we have put a lot of time into
+ensuring that 2.0 is mostly backwards compatible with 1.x, it is not
+COMPLETELY backwards compatible. There are differences that mean it
+is simpler and safer to migrate your configurations.
+
+ If you are upgrading an existing installation, please be aware that
+at least one default virtual server MUST be used. If you are
+upgrading from a previous version of FreeRADIUS, this change can be
+done by editing radiusd.conf, and wrapping all of the authorize,
+authenticate, etc. sections in one server block, as follows:
+
+...
+ server { # line to add
+ authorize {
+ ...
+ }
+ authenticate {
+ ...
+ }
+ accounting {
+ ...
+ }
+ ...
+ post-proxy {
+ ...
+ }
+ } # matching line to add
+...
+
+ If this change is not made, the server WILL NOT START. It will
+instead complain about "no server defined".
+
+ See "raddb/sites-available/default" for an example of how this
+should be done.
+
+
+4. CUSTOM INSTALLATION
FreeRADIUS has autoconf support. This means you have to run
./configure, and then run make. To see which configuration options
