Upgrade from v1.0.1 to v1.1.3

[PurpleCow]

Hi,

I am looking to upgrade one of my pligg sites from from v1.0.1 to v1.1.3 (latest version)
Are there any known issues to keep in mind? I will have a backup of existing site.

Is it simple straight forward to upgrade?

Thanks

Download the 1.1.3 package, unpack it on your desktop, head to the readme.html file and just read about Upgrading.

I can not say if it goes well or not, I just installed 1.1.3.

Excerpt from readme.html :

Backup your MySQL database
Backup your old Pligg CMS files.
Rename your template folder so that the data is not overwritted by upgrade files. If you use a template name that is not included with Pligg, skip this step.
Disable all of the modules from your admin panel. 
You will need to re-enable them after upgrade.
Delete all of the files from your server EXCEPT:
/avatars/ (entire directory)
/libs/dbconnect.php
/.htaccess
/favicon.ico
/settings.php
Upload all of the new files to your server. 
If you are able to I suggest uploading a zip file to the server and extracting it server-side. This will minimize the chances of files being corrupted during FTP transfer, which is a common issue.
Confirm that the CHMOD permissions for the following files or folders are all set to 777.
settings.php
/admin/backup/
/avatars/groups_uploaded/
/avatars/user_uploaded/
/cache/
/cache/admin_c/
/cache/templates_c/
/languages/
/languages/lang_english.conf
Run the upgrade from /install/upgrade.php
If there are no error messages, delete the /install directory from your web server.
Log in as a "god" level user.
In some cases you may already be logged in from your previous version of Pligg.
Either update your template to work with the latest version or navigate to /admin/admin_config.php?page=Template and change the template name to "wistie"
Re-activate the disabled modules from step 4, navigate to /admin/admin_modules.php

Do you really need to basically get rid of everything and then install. Couldn't it overwrite the main files like it said to do with upgrade from 1.1.2?

You don't need to delete everything off the server when upgrading, but sometimes it will help reduce the number of potential problems caused by failed or slow uploads. Removing the files using FTP first will usually make the upload go a lot faster because it doesn't have to overwrite every file.

My preferred method is to prepare a .zip file with all of my new files in it. Then I upload that to the root directory, and then unzip it using SSH. You can also unzip using software like Cpanel's file manager. That greatly reduces the chances of a file becoming corrupted due to FTP upload. It also makes it super fast getting the files on your server.

If you are using a template other than the standard Wistie template, you will need to upgrade it. Best method of doing this is by downloading the version of Pligg you are upgrading from (ex. 1.0.3) and then download the version you are upgrading to (ex. 1.1.3). Then use Winmerge software to compare the /templates/wistie directories. This will show you all of the template changes made. Then just apply those changes to your own template.
