Migrating wordpress site to new plesk server

Hi,

I am trying to migrate or copy my wordpress website from an older plesk managed server/via IONOS to a more powerful server also Plesk/IONOS. The website has grown and is slow, i am trying to increase site speed and efficiency for customers and SEO.

However i am having real difficulty and i have tried the migrate options available from Plesk/wordpress and also downloading and uploading using FileZilla. But i keep hitting walls and whenever i add the new host to my DNS on IONOS my website crashes until i remove the new host A records.

Not sure if this is the place for help on this, but would appreciate any feedback

Thank you

Dustin Toland
