FreeBSD MPS: Release Notes - What are the Known Issues?
This section includes information about backward compatibility of core services and the interaction of popular applications with
the versions of those services available for MPS v3, and corresponding applications available for MPS v2. It also includes
considerations when migrating from MPS v2 to MPS v3 and other existing issues.
Backward Compatibility
With the introduction of new versions of Apache, MySQL, and PHP, some elements of these new versions may not be compatible
with previous versions available with other MPS products, such as MPS v2. Considerations for these services and programs follow.
Apache
With Apache 2, the module interface has completely changed. Because of this, modules used with Apache 2 differ from their
Apache 1 counterparts. Scripts and programs written to interact with modules in Apache 1 may not function the same when
interacting with the corresponding module for Apache 2. For example, Apache 2 includes support for mod_perl2 instead of
mod_perl, the default for previous MPS implementations. Compatibility modules may be available for a specific Apache 1 module.
Consult the documentation for the module in question for further information about backwards compatibility of that module.
Apache 2 also introduces some configuration directives changes. For more information about directives changes, refer to the
Web addresses mentioned in Web Server.
MySQL
All Structured Query Language (SQL) syntax used in 4.x should function correctly in MySQL 5.x. However, it is always best to
perform a full database export (or dump) on the system running under 4.x and then import the information into the 5.x system to
ensure data is not corrupted. Other considerations when moving between MySQL versions 4.x and 5.x include the following:
The format of the standard mysql database (which keeps user and other essential information) has changed.
Support for some old types of tables has been discontinued.
Multi-byte support changed with 4.1x and may be significantly different.
For more information about changes in MySQL 5.x, refer to the Web address mentioned in MySQL 5.x.
PHP
Most scripts and programs created for PHP 4.x should function with PHP 5.x. Verify that scripts and programs function correct
when moving from a PHP 4.x environment to PHP 5.x.
The short tags configuration is disabled by default for PHP 5.x. This can be enabled in the /usr/local/lib/php.ini file.
Migration Considerations
Automated scripts to move sites or content from a different MPS product to the MPS v3 will be available at a later date.
Customers interested in migrating their sites and content must create any such scripts or perform such activities themselves
at this time.
Regarding CPX: Control Panel
For the CPX: Control Panel, on the Manage Services section of the System Administration module, the httpd service shows a
status of stopped when the service is running.
