Hi @premalatha_s,

Normally taht should work but, if you can't run the upgrade in that way, you can copy the files manually (isn't the best because if a file was removed you can't delete that file) but it will work.

Hi @premalatha_s,

Remeber to make a backup before change anything.

Hello @premalatha_s,

1. Take a backup of code and database.
2. If your Magento version is 1.9.0.1 then compare the directories of your Magento app/code/core folder with default magento1.9.0.1 so that we can know the modified or previously customized files.
3. Similarly, compare frontend/base files etc.,
4. After the above steps, copy the entire files and folders of default magento1.9.3.1 and paste in magento1.9.0.1
5. Remove cache and session and run front end.
6. If the new version has any new database tables it will install or any error occurs simply follow the system.log and exception.log or display errors will show the errors.
7. Test all front end and admin pages.

Note:- This upgrade will not effect the theme files.
