Migration of the CERN e-mail system to open source

CERN IT presentation on the e-mail migration (Indico).

What it anchors

• The target of the migration: around 40,000 mailboxes and 50–60 TB of mail data, moving from Microsoft Exchange to the open-source Kopano, chosen after market research, evaluation and proofs of concept, with a support contract with the vendor.
• It was among the first tangible outcomes of MALT.
