We completed the upgrade and it was not that difficult.  I was indeed 
surprised to see that about 95% of our configuration file worked 
unmodified.  All we had to to was look at the error messages and fix the 
syntaxes were applicable.  Most were related to rtpproxy or xlog statements.

Regarding the mysql database, we simply started with the new Kamailio 
schema.  Then we went table by table and added/deleted/renamed columns 
on the old schema so that it would match the new one.  We then exported 
the entries in the old database with mysqldump and then imported them 
into the new database.  We were only working with 5 or 6 tables so it 
did not take long either.
