I have migrated my prestashop 1.5.6 e-commerce site to a new server,
Process i did was just upload the files to new server and import the db.
I cleaned the Cache/smarty/compile and Cache/smarty/cache folders and left the index.php file.
I tried regenerating thumbnails from Preferences/images page but didn't work and gave "Internal server error".
I changed the process configuration to FcgidBusyTimeout 3600 in /etc/httpd/conf.d/fcgid.conf
I tried again to regenerate and this time, it is gave that : Original images not found in /img/p/1/2/xxx, But in reality all my images are in /img/p/xxxx.png
I tried using the Move Images to New image structure function in Preferences/images page and it created the structure but 1400+ images are not found now !!
Anyhelp will be more then welcome !

For others who may not yet get the answer
Go to Preference -> SEO and URLS.
There you will get a block for shop detail named as "Set Shop URL", There you have to change the details for Shop domain, SSL domain, Base URI as per your server details.
