RHEA-2016:2618 - Product Enhancement Advisory

Topic

An updated preupgrade-assistant-el6toel7 package that fixes several bugs and adds various enhancements is now available for the Extras channel of Red Hat Enterprise Linux 6.

Description

Preupgrade Assistant is a set of scripts and plug-ins that can assess your system before upgrading to the next major version of Red Hat Enterprise Linux. It checks for removed packages, packages with partially incompatible replacements, changes in libraries, users and groups, and various services. It then produces a report that assists you in performing the upgrade itself by outlining potential problem areas and offering suggestions about mitigating any possible incompatibilities. In addition, Preupgrade Assistant helps you install a new major release of Red Hat Enterprise Linux that is as similar as possible to your previous system. It also provides post-upgrade scripts, which will help you finish migration after the installation of a newer Red Hat Enterprise Linux release.

This update fixes the following bugs:

• Previously, when creating a diff between the current and the default configuration file "/etc/httpd/conf/httpd.conf", the arguments to diff were passed in the wrong order. As a result, the diff was reversed. With this update, the arguments are passed in the correct order, and the diff is correct. (BZ#1318572)
• Previously, the Preupgrade Assistant did not back up some configuration files that should have been backed up. With this update, the bug has been fixed. (BZ#1281452)
• Previously, initscripts were not handled by the initscripts module and almost all of them had to be handled manually. With this update, some initscripts are handled automatically while the information about manual handling of the others is printed, as before. In future, more initscripts will be handled by the module. (BZ#1365835)

In addition, this update adds the following enhancements:

• With this update, the TLS certificates for LDAP authentication on the original system are backed up and are available on the new system. (BZ#1358662)
• Previously, the "GRUB to GRUB2 migration" module contained only the information about the fix enabling the modification of boot parameters. With this update, the module also has information about expected manual actions after the in-place upgrade. (BZ#1229341)
• With this update, BIND configuration files on the original system are checked in detail for deprecated directives and syntax constructs as well as for differences in configuration defaults, and the configuration files are backed up.

This update also adds a feature that checks and backs up the configuration files relevant to running BIND in a chroot environment. For more details on how to run BIND in a chroot environment, see the link in the References section. (BZ#1274286)

This update brings further enhancements and provides more detailed information about the current assessment of the system and possible problems which you might encounter after the upgrade or migration to a new version of the system.

Users of preupgrade-assistant-el6toel7 are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
