Help with moving server please - cpanel to plesk

[Layton]

I am looking to move my site gr8-kitchenware.co.uk to a new server, going from cpanel to plesk.

I want to copy files and database and upload to a trial domain to make sure its all working.

My idea is to upload latest Prestashop version to new domain and then restore my saved files and database to this…..check it out make sure its ok.

Questions are;

1) I have some customized scripting….will these copy across ok when I restore?

2) Do I download my files from cpanel into a zip file…..then upload and extract?

3) Is this a sensible way of doing this?

Many thanks in advance for your help, it is truly appreciated.
