restore problem

hello everyone,
so i have my blog at a host and iam changin to a new host, so i backed up the database with skippy’s plugin
then installed and optimized everythin on the new host and restored the database via the PHPMYADMIN but now everyth is linked to the old host ?! for an example wen i click on a post it reveiws it from the old host

i guess i did smth stupid but i cant figure it out
any help would be appreciated
Thanks
