- Plesk for Linux
During migration Plesk shows following notice:
PLESK_INFO: Courier-IMAP is not installed on the destination server.
Please install Courier-IMAP by using Plesk Installer.
Courier IMAP is installed on the source server and Dovecot is installed on the target server, as can be seen in Tools & Settings > Server Components
Plesk Migrator bug with ID #PMT-3344.
This warning can be ignored, as Dovecot seamlessly replaces Courier IMAP.
The mail content will be migrated.
