If you are coming from a version earlier than the 01 May 2000 production release, please see TWikiUpgradeTo01May2000 first.

The current Beta version has these changes affecting the upgrade of the 01 May 2000 version:

• Improved search, i.e. search multiple webs.
• The changes script has been retired (related to new search).
• Reorganization of topics: The TWiki.Main web was split up into TWiki.Main and TWiki.TWiki web.

These are the steps you need to perform to upgrade the 01 May 2000 version to Beta: [ We assume export TWIKIROOT=/some/dir/ ]

• Unpack the beta zip file into some working directory:
  mkdir -p ~/tmp/
cd ~/tmp
unzip ~/TWiki20000909beta.zip

• Upgrade the TWiki document files ( twiki )
  • Move the document files to your TWiki root, i.e.
    mv ~/tmp/TWiki*.html $TWIKIROOT
mv ~/tmp/readme.txt $TWIKIROOT

• Upgrade cgi-bin scripts ( twiki/bin )
  • Rename your original twiki/bin directory, i.e.
    mv $TWIKIROOT/bin $TWIKIROOT/bin.old
  • Move the new scripts to your original twiki/bin location, i.e.
    mv ~/tmp/bin $TWIKIROOT/bin
  • Merge the changes in your current wikicfg.pm into the new wikicfg.pm. We suggest using diff -c to compared the two files if you have made heavy changes to the file, i.e.
    diff -c $TWIKIROOT/bin.old/wikicfg.pm $TWIKIROOT/bin/wikicfg.pm | less
  • In wikicfg.pm, change $wikiToolName from "TWikibeta" to "TWiki".
  • Restore any additional scripts you might have from the old directory, i.e.
    mv $TWIKIROOT/bin.old/somescript $TWIKIROOT/bin/
    (Note that the changes script is obsolete.)
  • In case you have basic authentication:
    • The TWikiRegistration topic moved from the TWiki.Main web to the TWiki.TWiki web. Change .htaccess to reflect the new location, i.e.
      ErrorDocument 401 /cgi-bin/view/TWiki/TWikiRegistration
  • Pay attention to the file and directory permissions (security issue)
  • Test your TWiki installation if you can view topics. (Ignore the %HTTP_EQUIV_ON_VIEW% you see on top of the topic, this will disappear after upgrading the template files.

• Upgrade templates files ( twiki/templates )
  • Rename your original twiki/templates directory, i.e.
    mv $TWIKIROOT/templates $TWIKIROOT/templates.old
  • Move the new templates to your original twiki/templates location, i.e.
    mv ~/tmp/templates $TWIKIROOT/templates
  • Merge the changes in your current template files into the new template files. To compare two files use
    diff -c $TWIKIROOT/templates.old/view.tmpl $TWIKIROOT/templates/view.tmpl | less
  • Restore any additional template subdirectories of your TWiki webs you might have and merge the changes.
  • Test your TWiki installation if you can view topics.

• Upgrade public files ( twiki/pub )
  • Move the new twiki/pub/TWiki directory to your installation, i.e.
    mv ~/tmp/pub/TWiki $TWIKIROOT/pub/
  • Pay attention to the file permissions of the TWiki directory and its subdirectory and files. The files must be writable by the cgi-scripts (usually user "nobody")

• Upgrade data files ( twiki/data )
  • Move the new twiki/data/TWiki directory to your installation, i.e.
    mv ~/tmp/data/TWiki $TWIKIROOT/data/
  • Pay attention to the file permissions of the TWiki directory and its files. The files must be writable by the cgi-scripts (usually user "nobody")
  • The following topics are new and most be copied to all of your TWiki webs: WebChanges, WebIndex.
    cp -p $TWIKIROOT/data/TWiki/WebChanges.txt* $TWIKIROOT/data/Main
cp -p $TWIKIROOT/data/TWiki/WebIndex.txt* $TWIKIROOT/data/Main
    Repeat this for all your webs. Pay attention to the file permissions.
  • TWikiRegistration moved from TWiki.Main to TWiki.TWiki. In case you customized TWikiRegistration , merge your changes back into TWiki.TWikiRegistration , then delete $TWIKIROOT/data/Main/TWikiRegistration*.
  • TWikiPreferences moved from TWiki.Main to TWiki.TWiki. Merge your changes to TWikiPreferences into TWiki.TWikiPreferences, then delete $TWIKIROOT/data/Main/TWikiPreferences*.
  • Modify the WebPreferences topics in all your webs to reflect the following:
    • WEBTOPICLIST should use WebChanges for "Changes", and WebIndex for "Index", i.e.
      | <a href="WebChanges">Changes</a>
| <a href="WebIndex">Index</a>
    • In case you want to exclude a web from a web="all" search: Set this new preference
      Set NOSEARCHALL = on
  • The WebSearch topics has considerable changes. Copy the one from TWiki.TWiki into all webs, or merge them if you made changes. To copy, do an edit-copy-edit-paste operation.
  • Change the WebHome topics in all your webs to reflect these changes:
    1. The "Changes" link should point to WebChanges.
    2. The "Topic index" link should point to WebIndex.
    3. Change the include of the web table to %INCLUDE{"TWiki.TWikiWebsTable"}%
  • Move your TWikiWebsTable topic from TWiki.Main to TWiki.TWiki., i.e.
    mv $TWIKIROOT/data/Main/TWikiWebsTable* $TWIKIROOT/data/TWiki
  • The following topics in the TWiki.Main web are depreciated (because they moved to TWiki.TWiki), but still need to be present in TWiki.Main because of existing links to these topics: FileAttachment, TWikiDocumentation, TWikiHistory, TWikiPreferences, TWikiVariables.
    It is recommended to edit these topics in TWiki.Main and replace the content with this line:
    This topic moved to %TWIKIWEB%.%TOPIC% in the %WIKITOOLNAME%.%TWIKIWEB% web.
  • The following topics in the TWiki.Main web are obsolete and can be deleted: BillClinton, GoodStyle, RegularExpression, TextFormattingFAQ, TextFormattingRules, TWikiAdministration, TWikiCategoryTable, TWikiEnhancementRequests, TWikiImplementationNotes, TWikiInstallationNotes, TWikiNotificationOfChanges, TWikiPlannedFeatures, TWikiUpgradeTo01May2000, TWikiUsernameVsLoginUsername, TWikiWeb, WelcomeGuest, WelcomeVisitor, WikiName, WikiNotation, WikiTopic, WikiWikiClones. Sample delete command:
    rm -f $TWIKIROOT/data/Main/BillClinton.*
  • In all your webs, change references to topics that moved to the TWiki.TWiki web:
    • Change topics: TWikiUsers , WebNotify , WebHome
    • With links to: TWikiPreferences , TWikiVariables , TWikiUsers , TWikiWebsTable and WelcomeGuest
