Why Kerio Connect Needs a Migration Tool

Moving off Kerio means moving years of mail, calendars and contacts. Manual copies drop fields and miss attachments, while the wizard migrates the mailbox with all data attributes and its folder hierarchy.

Manual or tool

Manual Export or Kerio Migration Tool

Kerio gives no one click route to other platforms. See how a manual export compares with the wizard.

Task	Manual export	Tool
Cost	Free	$99 one time
Data fields	Some skipped	All attributes kept
Folder structure	Often flattened	Hierarchy kept
Calendars	Lost in transit	Saved as ICS files
Contacts	Copied by hand	CSV and vCard 2.1, 3.0, 4.0
Progress	No tracker	Live status tracker
Large mailboxes	Slow and risky	No size limit
Targets	One platform	100+ IMAP clients and cloud apps

The single green row marks the case where a manual export still works.
