title: Trouble upgrading odoo 8 to odoo 9
body: <p>I have never used odoo, how do I upgrade from odoo 8 to odoo 9.</p>
  
  <p>EDIT: I have found the answer to this question and have posted the steps along. I will develop a efficient process write it down as well as any difficulties if anyone would like that message or post me.</p>
  
  <ol>
  <li><p>Backup the databases</p></li>
  <li><p>Backup the server folder</p></li>
  <li><p>Uninstall the odoo server</p></li>
  <li><p>Install the new version of odoo and after stop the odoo service</p></li>
  <li><p>Use a comparison tool to move changes from the Old addons folder to the new one. I use beyond compare for file and folder comparisons. This step probably will take more time around 30-40minutes tops to merge python and report files that were customized. Move existing modules in the old that don’t exist in the new addons folder.</p></li>
  <li><p>Upgrade the database. For linux, start the odoo server with the –update=all parameter. For windows, as an administrator open the command prompt (cmd).  Change to the odoo server directory and start the server with odoo-server.exe –update=all to update the modules. This process will take a short while (1-2minutes max) and the database won’t be accessible by the client</p></li>
  <li><p>After the database upgrade  you can start poking around your old modules you moved to the new to make sure that they where working. I had some  that where not working, reports screwed up, but majority where simple fixes. Finally, your up and running the latest version. This has taught me a major lesson, document all changes/fixes you make yourself to applications and also keep track of them in the source control. Now next thing I will be setting up my old local svn server to keep track of the changes I make to odoo and also changes I will be merging from the subsequent releases.</p></li>
