These are the steps you need to perform to upgrade the 01 May 2000 version to the current Beta version:

• Create a TWiki directory below the data directory.

• Delete the following files in your TWiki.Main installation:
  • BillClinton , GoodStyle , RegularExpression , TextFormattingFAQ , TextFormattingRules , TWikiAdministration , TWikiCategoryTable , TWikiDocumentation , TWikiEnhancementRequests , TWikiHistory , TWikiImplementationNotes , TWikiInstallationNotes , TWikiNotificationOfChanges , TWikiPlannedFeatures , TWikiPreferences , TWikiUpgradeTo01May2000 , TWikiUsernameVsLoginUsername , TWikiVariables , TWikiWeb , WelcomeGuest , WikiName , WikiNotation , WikiTopic , WikiWikiClones
• 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 , WelcomeGuest
• Move your TWikiWebsTable topic to TWiki.TWiki.
• Merge your changes to TWikiPreferences into TWiki.TWikiPreferences , then delete Main.TWikiPreferences
• In case you customized TWikiRegistration , merge your changes back into TWiki.TWikiRegistration , then delete Main.TWikiRegistration .
• In case you have authentication: Change .htaccess to reflect the new location of the TWikiRegistration , i.e.
  ErrorDocument 401 /cgi-bin/view/TWiki/TWikiRegistration
