 === 6. Steps specific to a given Trac version
 
+==== Upgrading from Trac 1.0 to 1.2 #to1.2
+
+===== Python 2.5 no longer supported
+
+Upgrade Python to at least 2.6 or 2.7, but not 3.0 or greater.
+
+===== Obsolete Plugins
+
+Trac has added functionality equivalent to the following plugins:
+* [https://trac-hacks.org/wiki/AdminEnumListPlugin AdminEnumListPlugin]
+* [https://trac-hacks.org/wiki/DateFieldPlugin DateFieldPlugin]: see the **time** [TracTicketsCustomFields#AvailableFieldTypesandOptions custom field type]
+* [https://trac-hacks.org/wiki/GroupBasedRedirectionPlugin GroupBasedRedirectionPlugin]: the default handler can set as a user preference.
+* [https://trac-hacks.org/wiki/LinenoMacro LinenoMacro]: see WikiProcessors#AvailableProcessors
+* [https://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin NeverNotifyUpdaterPlugin]: see [TracNotification#notification-subscriber-section notification subscribers]
+* [https://trac-hacks.org/wiki/QueryUiAssistPlugin QueryUiAssistPlugin]: see TracQuery#Filters.
+* [https://trac-hacks.org/wiki/TicketCreationStatusPlugin TicketCreationStatusPlugin]: see [#NewWorkflowActions]
+
+The plugins should be removed when upgrading Trac to 1.2.
+
+===== New workflow actions #NewWorkflowActions
+
+The ticket creation step is controlled with a workflow action. The default workflow has `create` and `create_and_assign` actions. The `create` action will always be added when upgrading the database. The `create_and_assign` action will be added if the workflow has an //assigned// state. You may want to edit your workflow after upgrading the database to customize the actions available on the //New Ticket// page.
+
+===== New permissions policy for read-only wiki pages
+
+Since 1.1.2 the read-only attribute of wiki pages is enabled and enforced only when `ReadonlyWikiPolicy` is in the list of active permission policies. If `[trac] permission_policy` has the default value `DefaultPermissionPolicy, LegacyAttachmentPolicy`, then `ReadonlyWikiPolicy` should be automatically appended to the list when upgrading the environment:
+{{{#!ini
+[trac]
+permission_policies = ReadonlyWikiPolicy,
+ DefaultPermissionPolicy,
+ LegacyAttachmentPolicy
+}}}
+
+If other permission policies are enabled, `trac.ini` will need to have `ReadonlyWikiPolicy` appended to the list of active `permission_policies`. See TracFineGrainedPermissions#ReadonlyWikiPolicy for additional details on the proper ordering.

 ===== Subversion components not enabled by default for new installations
+
 The Trac components for Subversion support are no longer enabled by default. To enable the svn support, you need to make sure the `tracopt.versioncontrol.svn` components are enabled, for example by setting the following in the TracIni:
 {{{#!ini

 }}}
+
 The upgrade procedure should take care of this and change the TracIni appropriately, unless you already had the svn components explicitly disabled.
 
 ===== Attachments migrated to new location
+
 Another step in the automatic upgrade will change the way the attachments are stored. Create a backup of the `attachments` directory before upgrading. In case the `attachments` directory contains some files which are //not// attachments, the last step of the migration to the new layout will fail: the deletion of the now unused `attachments` directory can't be done if there are still files and folders in it. You may ignore this error, but better to move them elsewhere and remove the `attachments` directory manually. The attachments themselves are now all located in your environment below the `files/attachments` directory.
 
 ===== Behavior of `[ticket] default_owner` changed
+
 Prior to 1.0, the owner field of new tickets always defaulted to `[ticket] default_owner` when the value was not empty. If the value was empty, the owner field defaulted to to the Component's owner. In 1.0 and later, the `default_owner` must be set to `< default >` to make new tickets default to the Component's owner. This change allows the `default_owner` to be set to an empty value if no default owner is desired.

 There are some significant caveats in this, such as accepting a ticket sets it to 'assigned' state, and assigning a ticket sets it to 'new' state. So you will probably want to migrate to "basic" workflow; [trac:source:trunk/contrib/workflow/migrate_original_to_basic.py contrib/workflow/migrate_original_to_basic.py] may be helpful. See TracWorkflow for a detailed description of the new basic workflow.
 
-===== Global Configuration
-In versions prior to 0.11, the global configuration was by default located in `$prefix/share/trac/conf/trac.ini` or `/etc/trac/trac.ini`, depending on the distribution. You may want to specify that file to inherit from when upgrading.  Literally, when upgrading you have to add an `[inherit]` section to your project's `trac.ini` file. Additionally, you have to move your customized templates and common images from `$prefix/share/trac/...` to the new location.
