Efficient way of transfer website over hosting
There are many ways to do this manually and using plugins. I need both Hosting access to move whole WordPress setup to new hosting. As we are moving file from one hosting to another we only need to move WordPress package along with Database. No need to change URLs or anything. However, need to be very careful with settings. I would use my scripts to quickly transfer files over server and export / import database. Extract files on new server and update database details into wp-config.php file. Login to back end and from settings > permalink settings need to refresh/save. I would also expert all the theme settings and widget in existing theme and import that to new server. Theme settings could be imported/exported thro' theme options and widget could be imported/exported using Widget Import Export plugins. Finally, change the DNS to point to new Hosting server from the Hosting control panel and website will be propagated from new server upto 48 hours. In case there will be not downtime
