One tool that can help you with you migration is the script live_ast
which is included with Asterisk as of 1.6.2 under contrib/scripts (but
you can simply fetch it with:
wget http://svn.digium.com/svn/asterisk/trunk/contrib/scripts/live_ast )

It allows you to "install" a separate copy of Asterisk onto the
directory live/ under your source directory. It will also create a
wrapper script live/asterisk that can be used as the asterisk binary for
most scripts. You can edit live/etc/asterisk/asterisk.conf to use either
configuration in /etc/asterisk or your own separate copy in
live/etc/asterisk/ .

This allows you to easily switch to 1.6.0.6 for testing and easily
switch between the production version and the testing version.
