I have never used odoo, how can I upgrade from odoo 8 to odoo 9.
EDIT: I found the answer to this question and posted the steps. I will develop an effective process, write it, as well as any difficulties if someone wants this post or publishes it.
Backing up databases
Server folder backup
Remove odoo server
Install the new odoo version and after stopping the odoo service
Use the comparison tool to move changes from the old add-ons folder to the new one. I use out of comparison to compare files and folders. This step will probably take more time about 30-40 minutes to merge the python and report files that have been configured. Moving existing modules in the old that do not exist in the new add-ons folder.
Database update. For linux, start the odoo server with the -update = all option. For windows as an administrator, open a command prompt (cmd). Change to the odoo server directory and start the server using odoo-server.exe -update = all to update the modules. This process will take a short time (maximum 1-2 minutes), and the database will not be available to the client.
After updating the database, you can start digging around your old modules, and you switched to the new one to make sure that they work. I had the fact that where it doesn’t work, the messages narrowed, but most of them have simple corrections. Finally, you start and run the latest version. This taught me a big lesson, document all the changes / corrections that you make by the applications themselves, and also track them in the original control. Now, the next thing, I will configure my old local svn server to track the changes that I make for odulation, as well as the changes that I will merge with subsequent releases.
