Migrated Blog but login still points to original domain

Hello,

I’ve recently been asked to migrate our entire blog to a staging site so that we can have outside developers work on it without making permanent changes to our real site.

The original site is https://www.peacepaint.com. I reinstalled wordpress at https://www.tralfam.com, went through mysql in cpanel, exported the entire database, and imported it into a newly named database on the cpanel at tralfam.com.

Now when I login at https://tralfam.com/wp-login.php, it takes me to https://peacepaint.com/wp-admin/ Is there any specific file you might know of that will allow me to fix this problem? Do I have to somehow Find all the “peacepaint”s in the sql file and replace them with “tralfam”s?
