Gregory's Server
The most reliable method would probably be to create an account on the new server and upload your follows before you do the actual transfer, and see how that affects your follow list.
Follows can always be uploaded through the import export process, it's at the start of the step by step guide.
(To transfer followers as well you need to do the full transfer, but follows (i.e accounts you follow) doesn't require this.)
Also, if worst happens, you can transfer back if you want.
