 | To upgrade an earlier TWiki version like 01 Sep 1999to version01 May 2000you should do the following things:
-- PeterThoeny? - 28 Apr 2000 Back up your system.
 Update the templates in the /templatesdirectory (and its subdirs):
 Take the templates of the latest distribution as the base and merge your changes back into it.
 Update the Perl scripts in the /bindirectory:
 Take the scripts of the latest distribution as the base and merge your changes back into it. Do so also for wikicfg.pmbecause it has important changes as well. Update topics:
 Copy the new Main. TWikiPreferences? topic (and *,vfile) into your TWiki.Main web. Customize the topic to your needs. Copy the new Main. WebPreferences, WebStatistics topics (and *,vfiles) into all your webs. Customize all WebPreferences topics to your needs (e.g. web color). Copy WebSearch into all your webs, or modify the existing ones. Reason: Some switches for search changed.
 Copy the TWiki documentation into your Main web: Topics TWikiDocumentation, TWikiUsernameVsLoginUsername, TWikiVariables, TWikiNotificationOfChanges?, TWikiCategoryTable, TWikiImplementationNotes, TWikiInstallationNotes?, TWikiUpgradeTo01May2000, TextFormattingRules, TWikiHistory .
 Copy the registration topic into your Main web:
 In case you are on an Intranet: Copy topic TWikiRegistration to Main.TWikiRegistration. Customize if needed.
 In case you are on a public server: Copy topic TWikiRegistrationPub to Main.TWikiRegistration. Customize if needed.
 Copy the Main. TWikiWebsTable topic (and *,vfile) into your Main web and customize it. Reason: The new release does not use the*.incinclude files anymore. Optionally: Search for %INCLUDE%'sin all your webs and change them to the new%INCLUDE{"file.ext"}%syntax. Note: Your old%INCLUDE:"file.ext"%syntax still works (the legacy rule is defined inwikicfg.pm.) Add the PoweredByTWikiLogo if TWiki is installed on a public web server.
