This section is meant to provide useful help in migrating your OpenSIPS installations from the 2.4.0 version to 3.0.0.
You can find the all the new additions in the 3.0.0 release compiled under this page. The ChangeLog may help your understanding of the migration / update process.

# opensipsdbctl migrate opensips_2_4 opensips_3_0
NOTE that the migration tool is available only for MYSQL databases!
NOTE that the default MySQL DB engine is now InnoDB!
