Wp Online Store – Prdouct list – restore mistake — immediate help needed.

Hello all,
Please help with Wp Online Store.

One of my site was using Wp online store, and was fully functional.
I wanted to move the site copy to another domain name also and hence followed the process to move the wordpress to a different domain.

After a couple of errors we get everything working but the Product list in the Wp online store was not imported.

— Here is what I did wrong —
I made a back up from the Wp-Online-Store > Tools > Database backup — from the old site, it gave a .sql file.

””””I simply uploaded it to my new site””””

Now– the new site — https://amzsolutionsonline.com — Is connected to the old site — bitlynk.com —
I can go the home page of the new site, but when logging into admin panel — it link me to bitlynk.com.

I know what I did wrong, I just need to know — how to undone this resotration ??
Please help.

Thanks, for all the help in advance.
Looking for immediate response.
