Upgrade Magento Community from 1.4 to 1.5 via SSH

February 28th, 2011 Posted by Public 3 comments on “Upgrade Magento Community from 1.4 to 1.5 via SSH”

It’s that time of year again. The new Magento stable release is out and it’s time to upgrade to the new version. I am upgrading on my staging site first and have of course made copies of everything in case it blows up.

I am upgrading to move to the “enhanced” import/export features in – supposedly I will actually be able to export my products (16,000+).

Step 1: Generate a SSH key on Mac

Navigate to “Utilities > Terminal”

In Terminal enter the following:

ssh-keygen -t dsa

Expected Response: “Generating public/private dsa key pair.”

Provide file to save the key:

Enter file in which to save the key (/Users/macuser/.ssh/id_dsa): id_dsa

Enter a passphrase (your local password – can be anything)

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

If successful:

Your identification has been saved in id_dsa.
Your public key has been saved in
The key fingerprint is:

Step 2: Locate the key in your file directory and open it with a text editor (I used bluefish).

Copy all text and add the text to the “Public Key” configuration at your web host. This step creates the secure connection between your server and local machine.

Step 3: Load SSH key in terminal

ssh-add /Users/macuser/id_dsa

– enter passphrase

Step 4: Connect to your server

ssh <user>@<domain>.com -p<ssh port>

Step 5: If connected correctly your prompt will change the user provided in step 4. Type “ls” to list folder contents on your server.

Step 6: Download Magento

Step 7: Extract tar file

tar -zxvf magento-

Step 8: list files again and look for folder “Magento”

Step 9: Copy extracted files over existing Magento installation (MAKE SURE YOU HAVE A BACKUP)
cd magento
cp -rf * ../public_html

Step 10: Try to load the site at your URL. If you have permissions issues or 500 errors try these fixes:
– I also had to look at the error logs in my cpanel to figure out the folder that had too high of permissions. For me it was ‘erorrs’ t0 fix I did a chmod 755 on that folder.

Step 11: Load the front end URL for your store to check to see if your template files work in version 1.5+
I had the following error:
Fatal error: Call to a member function toHtml() on a non-object in /home/../public_html/app/code/core/Mage/Core/Model/Layout.php on line 529
– Googled Fix:
– This worked for me

Step 12: Login to your administrative interface (usually http://<domain>/admin)
– Once you login you should see version in the footer (upgrade is done)

Step 13: Clean up the temp files

cd ../
rm -rf magento
rm magento-
