The Isotope eCommerce Migration Tool takes care of updating your Isotope eCommerce 1.4.8 database to Isotope eCommerce 2.2.*. Please note that it does only support this update path, other versions are not supported (yet)!
There are two different installation methods to get the Migration Tool up and running. Choose the one that works best for you. For both of then, after you uploaded the file(s) into the root directory of your Contao installation you then have to enter the mentioned URL to execute the migration tool.
You can download a ".phar" file which represents the whole Migration Tool within one single file. Note that executing Phar files imposes some requirements on your server infrastructure and might not work for you. In such case, use the installation method "regular archive".
URL to execute the migration tool: http(s)://your-domain.tld/name-of-the-phar-file.phar.php
You can download the Migration Tool as a packed archive from GitHub and upload the whole directory containing all the necessary files to your server.
URL to execute the migration tool: http(s)://your-domain.tld/name-of-the-directory/
You are now about to migrate data of your online shop. This is not a trivial task and if you run into errors it might happen that you need to start over. Having backups is thus an absolute must!
Once you installed it, the Migration Tool will explain all the necessary steps you have to take. Note that there are tons of things you have to do which the Migration Tool cannot do for you. Especially when you heavily customized your 1.4.8 installation (lots of template modifications, third-party extensions) the update will become a time-consuming task! In any case, the update from version 1.4.8 to 2.2.* will not be a piece of cake!
