upgrading from 1.7 to 1.9 magento

Question

i need to upgrade my magento store form 1.7 to 1.9. I am very new to magento, SSH and mysql. I was just wondering what is the easiest way to upgrade with breaking my website.

Thank you

Answer 1

Magento 1.x upgrade instruction using SSH or Command line:

1) Go to your Magento root directory

cd /path/to/your/magento/folder

2) Enable Maintenance mode for your Magento site

For this, you have to create an empty file named maintenance.flag in your Magento root directory.

touch maintenance.flag

3) Clear Cache & Sessions

rm -rf var/cache/* var/session/*

4) Check Compilation & Disable it if Enabled

Check Compiler Status

php -f shell/compiler.php -- state

If the Compiler Status is Disabled then you can skip this step and move on to the next step.

If the Compiler Status is Enabled then you have to disable it with the following command:

php -f shell/compiler.php -- disable

5) Give write permission to all Magento files and folders

chmod -R 777 .

6) Give 550 permission mage file which is a shell script file. With 550 permission, we are just making the file non-writable + readable & executable by user and group only.

chmod 550 ./mage

7) Change config settings to stable

./mage config-set preferred_state stable

8) Upgrade Magento

You can list all the installed packages with the following command:

./mage list-installed

You can list all the upgradable packages with the following command:

./mage list-upgrades

The following command will upgrade all the packages:

./mage upgrade-all --force

It will take some time to complete the upgrade.

9) After completing the upgrade, we should reindex all data.

php shell/indexer.php reindexall

10) Then, clear cache and session again.

rm -rf var/cache/* var/session/*

11) Enable Compilation only if it was Enabled before upgrade

Check step 4) above.

If Compilation was not enabled in step 4) then you can skip this step and go to next step.

If Compilation was enabled for your website and you had disabled it at step 4) then you have to Enable it with the following command:

php -f shell/compiler.php -- enable

12) Before the upgrade, we have changed the permission of all files and folders to 777. You should also give proper permission to all files and folders of your Magento site.

Convert files permission to 644 and folders permission to 755

find . -type f -exec chmod 644 {} \; && find . -type d -exec chmod 755 {} \;

Give read-write full permission, i.e. 777 to var and media folders.

chmod -R 777 var media

Give 550 permission to mage shell script file

chmod 550 ./mage

13) Check the versions of the installed modules. The modules should show the latest version as they are already upgraded now.

./mage list-installed

14) List the upgradable modules (modules that need an upgrade). This should result in a message saying No upgrades available because all modules have been already upgraded to the latest version.

./mage list-upgrades

15) Disable Maintenance mode to make the site Live.

rm -f maintenance.flag

This will delete the file maintenance.flag and then the site will be live again.

You can now login to Magento admin and see the Magento version displayed in the footer section. It should show the latest version number.

Upgrade Roadmap for CE 1.9.0.1 from 1.7

1. take a backup of current database and current 1.7 code.
2. download latest magento from the http://www.magentocommerce.com/download
3. remove all folders and files from your 1.7 code (but you should have backup somewhere) and place all folders and files from the 1.9.

4. now from your 1.7 merge your following folders into the 1.9

   • Community app/code/community
   • Local app/code/local
   • Media
   • your theme or package (app/design/frontend/default/<your theme> or app/design/frontend/<your package>)
   • custom folders from Skin (both for adminhtml and frontend).
   • copy your custom xml files from app/etc/modules/ to current app/etc/modules/
   • any custom admin theme folder from adminhtml/default/yourtheme.
   • copy your custom folders from adminhtml/default/default/ (1.7) to adminhtml/default/default/ (1.9).
   • custom js files if any from app/js/.

5. now go to app/etc/local.xml.Edit database details there. put your database username and password and database name.

6. now check the site. it's done.

Upgrade can be done by following these steps(if there are lot of custom modules and you want to ensure your code does not break)

1.Download the latest stable version of your Magento instance. 2.From your older copy, starting copying your custom modules from

            app/etc/local.xml
            app/etc/modules/
            app/community/
            app/local/
            app/design/frontend/{{package}}/{{theme}}, any custom template files 
            in default/default/ theme or base/default/ theme needs to be copied.

            adminhtml/default/{{custom theme}}
            adminhtml/default/default/
            skin/frontend/{[package}}/{{theme}}/{{css|js|images}}
            same for adminhtml if added any
            copy custom files from
            js/

3.Make changes to your local.xml and connect it to your older magento database.

Once you run Magento'instance, any core set up updates will be made using the setup files in your core extensions.

PS:- This method runs when you have followed all standards possible i.e no core modifications, correct class rewrites, no changes in index.php,Mage.php etc Also, if some of the third party extensions if give error, need to update them.

Hope it helps! And if you do try out..let me know how it goes!

Answer 4

The other answer is dangerous and should be taken with care make sure you create a dev server the following article explains

http://www.magentocommerce.com/wiki/groups/227/moving_magento_to_another_server

Answer 5

Current Version Magento CE 1.7.0.2

Admin panel -> System -> Magento Connect -> Magento Connect Manager

Check for Upgrades

Mage_All_Latest -> select Upgrade to 1.9.0.1

You are done!

You should be able to upgrade directly.

As always, third-party extensions and local customizations need to be taken into account, make a proper backup, etc.
