Does an Organization migration affect my email services?
Email services such as Email-To-Case, Email to Salesforce or Email to Apex are used for inbound email processing. During a migration these services are unavailable however once the migration has completed no action is required for the user to re-verify or re-configure even though the instance has changed.
Note that all Email Services (E2C, E2S and E2A) created after Spring '12 have the instance, that they were initial created on, appended within their domain part. This does not change to the new instance prefix after a migration.
