Post-migration activities

Finally, some steps need taking for your store to go live. Here is the checklist to set up an OpenCart store after a platform migration.

1. Choose a theme from your OpenCart store

If you want to maintain the same design in your new OpenCart store, you should check whether the old theme is compatible with your current OpenCart version. Otherwise, contact your theme provider or choose a similar theme out there.

OpenCart offers a variety of themes both free and paid for you to choose from. Check out our article here, we have listed out 8 best themes for OpenCart ever.

3. Run recent data migration

When transferring data with LitExtension or configuring your new store, your source store will be operating normally without any interruption. Accordingly, you can still receive new orders, customers, or add new products throughout the data transfer.

Recent data migration is a function of LitExtension that allows you to migrate new-formed entities in the old OpenCart store to the new one.

This video will show you how to do it:

4. Change DNS and switch domain

Domain name system (DNS) is the phone book of the Internet. Your DNS settings provide the link between your old custom domain name and the IP address of the network. When you are setting it up, you will need to get your DNS settings updated to direct to the new IP address. In fact, the easiest and fastest way to do it is to contact your old hosting provider.

Luckily, we also have clear guidance in switching domain after the migration. Let’s check out to get your job done easily.

Final words
