They did migration and basically I had to do nothing. The migration was delayed because of a bug in the Cloudways console system affecting all users, as soon as they fixed, they started to do the work. While installing my existing SSL, they did a small mistake and site showed security error. However, it was fixed and later the redirection wasn’t working, and they fixed it as well.
All looks good now. Site loads in 2s compared to 5s on hold host with no change in code!
