What is business email migration?
Business email migration is the process of moving existing mailboxes and historical email from one email platform to another. When a company changes its hosting provider or business email service, preserving existing messages is one of the most important parts of the transition.
IMAP migration allows folders and messages to be read from the existing server and transferred into a new email environment. This method is commonly used for cPanel, Plesk and other systems that provide standard IMAP access.
What should be prepared before migration?
The destination mailboxes should be created first. The source IMAP server, username, port and security settings can then be tested before any data is moved.
Analyzing the number of folders and messages before migration also helps estimate the amount of data that needs to be transferred.
When should DNS records be changed?
A safer approach is to prepare the new environment and migrate historical messages before changing the MX records. The existing email service can continue operating while the migration is being prepared.
After DNS changes are completed, new email begins arriving at the new server. The old service can remain available temporarily for final verification.
How should historical email be stored?
Long-running business mailboxes may contain thousands of messages. Instead of consuming active mailbox storage with every historical email, older messages can be stored in a dedicated archive while remaining accessible when needed.
