If you are an existing X-Cart v4 (aka XC4) store-based owner and want to upgrade it to X-Cart v5 (aka XC5), you can do it using a special X-Cart v4 to v5 Data Migration Wizard. This wizard is aimed at helping a store owner to migrate data from an XC4 based store to XC5. Besides that, it will be necessary to install a fresh X-Cart 5 store beforehand and re-implement any possible custom features manually afterward.
Basically, a store owner has three possible routes to do the upgrade:
Do the upgrade on their own (DIY option);
Hire X-Cart Team to perform the upgrade (Professional and Custom options);
Hire a 3rd party company to perform the upgrade (DIY option + whatever agreement a store owner comes up with 3rd party).
You can check the detailed description of each option on our website x-cart.com.
If you have decided to do the XC4 -> XC5 upgrade on your own, follow the steps below:
