What do I need to get ready if I am moving from another host?

You need to make sure you exported the DNS settings in your DNS manager. Failing that, at least have a screenshot of the DNS settings before you make any changes to it.

You need to make sure you have a copy of the website available as a file on your computer - not stored on ManageWP, or some other place where you have no access to.

Next make sure you take a screenshot of the Permalinks option in the original website, so you know what Permalink type was used.

Then follow the rest of this guide by ServMask for migrating the website using their All-in-one migration plugin on WordPress.

You can use other plugins, but we found All-in-one migration plugin to be the fastest and most importantly, most straight forward (read: no learning curve).
