Here is a simple check list to get you started:
- Any permanent records you need from your old host should be screen captured or printed, such as past billing invoices you may need.
- Archive any emails you need to save permanently, but are moving to AdriaHost. This is important because normally emails cannot be migrated. You can simply make a POP3 connection to a mail account; doing so downloads the emails to your local machine.
- Download copies of all your current website files and databases. This can come in handy later when you cancel the other host and then discover you are missing something.
