Upgrading CubeCart is usually straightforward, but stores with large inventories or limited server resources may need a little extra preparation.

Server Resources to Check Before Upgrading

PHP Setting Minimum Recommended for Large Stores
memory_limit 128M 256M or higher
max_execution_time 30 120 or higher
upload_max_filesize 8M 32M

These values can usually be adjusted via your hosting control panel or php.ini file.

Large Store Considerations

  • Stores with thousands of products may take longer to complete the upgrade process.
  • The upgrade may need to run database migrations which can be resource-intensive on very large tables.
  • If the upgrade times out, increase max_execution_time and try again — it will resume where it left off.

Before You Upgrade

  1. Back up everything — database and files. See our backup guide.
  2. If you have custom code modifications, review our guide on upgrading a modified store.
  3. Check the release notes for any version-specific instructions.
