Use this page to track migration issues for data moving from 1.5.x to 1.6. This information may be used in a migration script or may just prove useful to site developers trying to migrate.
In 1.6 the components and modules tables are removed in favor of a unified extensions table and core components are given a new set of numbers starting with 1.
Third party components start with xxxxx.
Every template will need to have one default record inserted into the template_styles table with the default parameters.
