Upgrading to Clerk.js 2 on Magento 1 See how to get the flexible Clerk.js 2 setup on your webshop. Stefan Lorenz Olsen
However, since the two versions work slightly differently, you need to follow these steps to successfully upgrade.
Step 1: Converting Designs
Since Clerk.js 2 has a different approach Designs, you need to create new ones.
You can create your Clerk.js 2 Designs in one of two ways:
1. Use the intuitive Design Editor to create new Designs, as described in the following points.
2. Convert your old Designs. Follow this guide to see how to do it.
1.1 Start by going to my.clerk.io -> Recommendations / Search -> Designs and click New Design:
1.2 On the following screen, give your Design a Name (we recommend adding "V2" so it's obvious that you are using Clerk.js2).
1.3. Choose Design Type: Product Slider (Design Editor), Exit Intent, or Product Slider (HTML).
1.4. When you are done, click Create Design
1.5. In the Design Editor, click any of the existing elements like the name, image, button, etc. to edit it, or drag-and-drop new elements to the Design to add more information about products.
1.6. Click Save Design when you are done, and go to Step 2 in the guide.
1.7. Lastly, go to Recommendations / Search -> Content and change your Clerk.io Content to use your new Design.
1.8. Click Update Content. This will temporarily cause them to not show up on your webshop until you are done with Step 2. Choose the new Design for all Content that should be updated.
1.9. There! You are now ready to switch over to Clerk.js 2.
Step 2: Upgrading your extension
If you already have the latest version of the Clerk.io Magento extension you can skip this step.
You can download the latest extension from this link:
2.1. Save any changes to extension files
Before you attempt to upgrade, make sure you have either:
Saved the changed files locally on your FTP or
Made a backup of any changed files, that you can carry over to the new extension.
Usually, the files that most developers change, are Product.php and Productbase.php, which control product attributes.
These files are found here:
2.2. Deactivate and uninstall existing extension
Before attempting to upgrade, it is very important that you do this:
2.2.1. Deactivate the old extension in Magento's System->Configuration->Clerk->Settings page. Simply set Enable to No and click Save Config.
2.2.2. Afterwards, uninstall it either through Magento Connect or by deleting the files
from FTP if you installed it directly here.
Otherwise, your Configuration page might stop functioning and neither extension will work afterward.
2.3. Install latest extension
Lastly, install the latest extension again, and move any files you have backed up, to your FTP server.
Your configuration should be saved, even when installing the new version. Check System->Configuration->Clerk to make sure that everything is still there.
Now you have the latest version of Clerk.io for Magento installed, and Clerk.js 2 is running on your webshop!
