What are you using to view and chart your power usage?

Do you have a custom domain name? If so, that makes it a bit more complicated as you’ll want to transfer DNS as well.

For DNS, I recommend looking at services like NameCheap that specialize in that. They’ll have some documentation around how to transfer DNS registration. You should be able to find other options for DNS searching this subreddit as well.

The second thing will be email hosting. One of the more popular ones out there these days is Fastmail. They have some documentation about how to migrate your emails over which is basically just allowing for an IMAP connection. Other email providers can also be found by searching through this subreddit.

Lastly, I would do these things one at a time. Migrating emails might be easier to do first, then update all the DNS stuff to point to your new server, then change registration of DNS. Reaching out to the DNS and Email providers, their support crews should be able to help fill in specifics of how to do that.
