I'm contemplating to buy this extension from Firebear studio:
https://firebearstudio.com/the-improved-import.html
In order to move products from Magento 1.9.4 to Magento 2.
They have replied the following:
In regard to Magento 1. You can use default magento export or in addition our free extension
https://github.com/firebearstudio/iimagento1
Note. This extension is no longer supported and we do not provide services to install and configure this extension.
Now, I've gone to that GitHub page, clicked EVERYWHERE and I can't find any installation instructions! How do I install this? Do I just upload the 2 files via FTP? How do I start the extension? Why does it not include any installation instructions while at the same time, the company who created it and points me to it, provides NO support?
UPDATED on June 16th, 2023:
I've attempted to do what @Sohel Rana suggested = created the directories and uploaded the files as listed here:
https://github.com/firebearstudio/iimagento1/find/master
Then, I went into the Admin panel, done a reindex from the Admin panel and when I clicked to Clear Cache in the Admin panel, it (both front and back end) went into Error 404.
I then deleted the Cache and var folders, re-indexed and cleared Cache via SSH but Error 404 stayed on.
I even asked our hosting to Clear Cache and re-index - they have done that but the Error (404) remained.
I had to removed the folders and files I've put in and then the site (front and back end) came back.
What have I done wrong and what do I need to do to make this work?
