[SR-Users] Upgrade from Sip Express Router 0.9.6

[Andres]

How would one even approach the daunting task of upgrading a fully 
operational Sip Express Router 0.9.6 installation with thousands of 
users that has been running unmodified for over 10 years.

I would like some pointers on how to approach the mysql database 
migration from the old schema to the Kamailio 4.2 schema.  I sure hope I 
don't have to start from scratch.  Maybe somebody has already done an 
upgrade script?

Regarding the config file, I will certainly have to rewrite it but I was 
wondering if there was a list of deprecated commands or syntaxes that 
would no longer be valid and their equivalent replacement.

Thanks,
