The first step of your X-Cart v4 based store migration to X-Cart v5 is the environment preparation.
The preparation step includes:
If the Wizard fails to find the data to migrate automatically from XC4, but you need to have these data in your new XC5 based store, transfer such data manually after the main data migration is complete. If you need help, contact X-Cart Team.
Checking the current server for compatibility with XC5 system requirements and enough disk space to run 2 X-Cart stores at a time. For details, see Meeting the Server Requirements for X-Cart 4 to X-Cart 5 Migration.
If your current server needs enhancements either in properties or in disk space or even in both, make sure to upgrade the current server or switch to a better one, or perform the upgrade on your local machine if it suits the requirements.
Installing a fresh X-Cart 5 based store as described in the Installation Guide.
Do not apply any customizations to X-Cart 5 before running the migration process, and also make sure to remove all demo data from the installation. You can remove existing data from X-Cart via System tools -> Remove data section of your X-Cart 5 Admin area.
Fine-tuning X-Cart 5 advanced settings for a smooth migration process. For details, see Advanced Settings.
All the preparation steps are described in detail in the guides of this section.
