    • Clearly you need to point it to a location where there is enough space
    • If you have symlinks under your data/ directory in your existing installation, these are reproduced as actual directories in the new structure. It is up to you to pull these sub-directories out again and re-symlink as needed
  • UpgradeTwiki doesn't deal with custom templates or Plugins, you will have to reinstall these in the new installation.

Line: 94 to 95
 If you followed the recommendations and avoided modifying any distributed files, then this is quite straightforward:
  1. Follow the installation instructions, and install the new release in a new directory.
  2. Copy your local webs over to the data and pub directories of the new install

  1. Copy over your bin/setlib.cfg and lib/LocalLib.cfg files

    • Be careful to copy over the user topics and TWikiUsers?.txt in the Main web
  1. Copy over your bin/LocalLib.cfg and lib/LocalSite.cfg files
  2. Copy over any local files you created (such as .htpasswd and .htaccess files)
 
  1. Point your webserver at the new install.
If you changed any of the distributed files, you will have to continue from Step 5 above.
