How complex is the SER configuration? SER couldn't do that much, by the standards of the modern feature set, so there may not be much to port. :-)

It is very simple.  I am more concerned about the procedure to migrate the thousands of mysql entries from one version to another.  If I have to write a script I will but before I do that I wanted to check in an see if somebody has already done it even if for an older version of Kamailio.

The database structure from ser 0.9.x is closer to current kamailio database in many aspects than to ser 2.0. I don't know what tables are you using, but subscriber, usr_preferences or grp should be pretty compliant. Maybe you ca list here what modules are you using.

The location needs to changed, but that is something which fills itself. You can first lower the max expires for registrar/usrloc modules so you force phones to register more often. Then restart with kamailio, and phones will register quickly after, populating location table.

Also, you need to set appropriate version values in 'version' table.

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.
