How to downgrade broken nodewords 1.1+ to 1.0 for a smooth upgrade to 1.3

This is a documentation issue for the reason that many asked how to downgrade to a previous stable 1.0 version.

The main reason why this is written here - is that 1.1 and 1.2 releases have deleted many if not all of your previously entered nodewords data and the module settings and there is no way to recover this data without restoring a backup.

Required:

• A valid backup of your Drupal site having Nodewords 1.0 installed. If you don't have a backup, there is now way to recover!

Step by step instruction:

1. Disable all Nodewords modules (Basic meta tags, Extra meta tags, Site verification and Nodewords) with version 1.1 or 1.2 or other DEV versions up to <1.3 at admin/build/modules.
2. Uninstall the modules Basic meta tags, Extra meta tags, Site verification and Nodewords at admin/build/modules/uninstall
3. Remove the nodewords folder from your installation. Typically it can be found in the folder sites/all/modules.
4. Execute DELETE FROM variable WHERE name IN ('nodewords-repeat', 'nodewords-use_front', 'nodewords_page', 'nodewords_story'); on your database. You need to see that 4 rows have been affected (deleted). If you use a table prefix, prepend variable with your table prefix. You can execute this query via MySQL Query Browser or myPHPAdmin, whatever is your preferred tool for DB administration.
5. Install Nodewords 1.0 to your modules folder e.g. sites/all/modules.
6. Enable Meta tags 1.0 module (this is Nodewords)
7. Restore the table nodewords from your backup and replace/overwrite the existing table. You can use MySQL Administrator for this task and go to Restore > Restore content by selecting the nodewords table only
8. If you haven't changed any settings in your Drupal installation that are saved in "variable" table you can restore "variable" table the same way. Otherwise you need to extract the 3 settings from your SQL backup file by searching for 'nodewords', 'nodewords-repeat' and 'nodewords-use_front'. Replace below with your settings and execute the query on your DB server.

   Example:

   INSERT INTO `variable` (`name`,`value`) VALUES 
    ('nodewords','your settings array is here...'),
    ('nodewords-repeat','i:0;'),
    ('nodewords-use_front','i:1;');
   

9. Clear all caches in admin/settings/performance.
10. Finished. Now you are able to review your previous meta tag settings.
11. Wait until Nodewords 1.3 final has been released.
12. Upgrade smoothly to 1.3 without loosing any data or setting. :-)

@Kiam: Please think about adding this to a doc page or the modules readme themself.

As written in #1 - no 2 - You need to UNINSTALL the module before the restore! This will remove all tables. There cannot be any stale table.

After you uninstalled (this does NOT mean - ONLY remove the folder!) check if there is a nodewords table in the database. If you have it - you haven't uninstalled. Additional - you should not use DEV versions and you need a backup from nodwords 1.0 - not any other!

Never seen this myself yet... maybe something that has changed after 1.3beta5, but I'm only guessing...
