Database Prefix

[Erica]

hiya
I had zencart installed and working on one domain name.
I have now decided to change hosts and to put the install on a different domain.
Before I cancelled my hosting on domain 1, I backed up all the files and also backed up the database.
I have installed zencart on domain 2 and am in the process of transferring the old files to the new domain.
I deleted all the database entries on the new install and imported the old database sql file from domain 1.
the problem i am having is this:
when I installed zencart on domain 2 it asked for domain prefix and i put esparkle_
when i import the previous database, the tables (or whatever they are called) have no prefix on them. I cant see a way to rename them and add esparkles_ to them, so is there a way i can go back and delete the esparkle_ prefix from the installation of zencart or do i have to delete and start over ?

does all that make sense?

Many thanks for any help you can give
